I'm using more than one TabContainer on a page in an ASP.NET project and I noticed a really strange behavior: when the page is loaded the focus jumps to the last TabContainer on the page, causing it to scroll down. I don't explicitly focus on any control so I don't understand where this is coming from. I also switched places between the controls and it is always the last one that is focused.
The TabContainers don't have any fancy settings, this is basically what they look like:
<cc1:TabContainer ID="tabContainer" runat="server">
<cc1:TabPanel runat="server" HeaderText="Header1" ID="tabPanel1" TabIndex="0">
<HeaderTemplate>
<asp:Label ID="lblTab1" runat="server" Text="Tab1"></asp:Label>
</HeaderTemplate>
<ContentTemplate>
... (anything goes here, it still doesn't work)
</ContentTemplate>
</cc1:TabPanel>
<cc1:TabPanel runat="server" HeaderText="Header2" ID="tabPanel2" TabIndex="1">
<HeaderTemplate>
<asp:Label ID="lblTab2" EnableViewState="False" runat="server" Text="Tab2"></asp:Label>
</HeaderTemplate>
<ContentTemplate>
... (anything goes here, it still doesn't work)
</ContentTemplate>
</cc1:TabPanel>
</cc1:TabContainer>
I know I can set focus on a control, I tried it but the page first scrolls to the tab container and then returns to the focused control (it doesn't look good). I tried this to set the focus to another control:
<body id="main" onload="javascript:document.getElementById('lnkLogout').focus();">
Is this the standard behavior for the TabContainer? How can I get rid of it?
Place script below right after ScriptManager control:
<script type="text/javascript">
Sys.Extended.UI.TabContainer.prototype._app_onload = function (sender, e) {
if (this._cachedActiveTabIndex != -1) {
this.set_activeTabIndex(this._cachedActiveTabIndex);
this._cachedActiveTabIndex = -1;
var activeTab = this.get_tabs()[this._activeTabIndex];
if (activeTab) {
activeTab._wasLoaded = true;
//activeTab._setFocus(activeTab); -- disable focus on active tab in the last TabContainer
}
}
this._loaded = true;
}
</script>
Try this out. It helped me:
window.Sys.Application.findComponent('<%=tabContainer.ClientID %>');
tabContainer.set_activeTabIndex(1); ( //Here set the id of the last tab that is the index of the last tab. Index will start with 0 upto last - 1 as in array.. )
This is an old thread, but it never got resolved – here or in any of the other threads I found – and I had the same problem.
I fixed it by putting my javascript in the body element: onload="scrollTo(0,0);"
You can set focus server-side to avoid the page jumping around.
Try this in Page_Load:
PageUtility.SetFocus(foo);
Also check you whether you are setting Page.MaintainScrollPositionOnPostback.
Let me know if that helps.
UPDATE - you can simply call .Focus() on whatever control you want to be in focus by default.
eg: YourControlToFocus.Focus()
I had a similar problem, but I found a more simple solution.
In the case you use a:
<asp:toolkitscriptmanager ID="ScriptManager1" runat="server">
</asp:toolkitscriptmanager>
and more panel in the tab container ( 3 for example):
<asp:tabcontainer runat="server" ID="tc1" ActiveTabIndex="0" >
<asp:TabPanel runat="server" ID="TB1" Height="250" >
<asp:TabPanel runat="server" ID="TB1" Height="250" >
<asp:TabPanel runat="server" ID="TB1" Height="250" >
For example, you can use the property:
ActiveTabIndex="0"
OR
tc1.ActiveTabIndex = 2 'code behind
Where the integer is the ID of the tab you want to Focus.
It works for me! I Hope I can Help someone!

I am having a problem with CKEditor inside an update panel in asp.net.
I have tab control on page with multiple CKEditor's i.e one ckeditor in each tab.
string scriptAdd = #"var editor = CKEDITOR.instances['ctl00_ContentPlaceHolder1_faqeditor']; if (editor) { editor.destroy(true); } CKEDITOR.replace('ctl00_ContentPlaceHolder1_faqeditor');";
ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "", scriptAdd, true);
The above code snippet helps in rendering the editor in update panel. But when a postback is done it still shows the earlier value and not the changed one i.e the editor does not reflect the changes made after the tab is changed in the update panel.
The same thing works perfectly fine without update panel.
Is there any solution for this problem?
just force ckeditor to update the textarea on change :
var ckEditor = CKEDITOR.replace('ctl00_ContentPlaceHolder1_faqeditor');
ckEditor.on("change", function (event) {
event.editor.updateElement();
});
Sorry for the late response on this, but the answer may be helpful to others as well. You also need to do the following in code behind:
ScriptManager.RegisterOnSubmitStatement(this, this.GetType(), "updatescript", "CKEDITOR.instances['ctl00_ContentPlaceHolder1_faqeditor'].updateElement();");
Hope this helps.

Add editor inside a div with visible="false"

it's works fine for me
I have a repeater with a RadioButtonList inside the ItemTemplate, but when the RadioButtonList.OnSelectedIndexChanged event fires it generates a full postback. What have I done wrong in my code below? How can I get the OnSelectedIndexChanged to generate an Async Postback?

This is a real-world use case. I have a page with Repeaters, Ajax Accordions inside of other Accordions, Update Panels inside other Update panels, you name it. The page works great, except when I want to update one of the Accordion panels with my RadioButtonList (RBL). Even with the RBL inside an update panel, it causes a postback of the entire page. I tried everything. I finally realized it wasn't me when I noticed my buttons would work just fine. I figure it must be a bug in either the framework or the Ajax Control Toolkit. I did find people reference this link all over the web (http://blog.smarx.com/posts/the-case-of-the-radiobuttonlist-half-trigger.aspx), but this link from 2007 is dead now and probably no longer applicable, so that's no help.
What I ended up doing was going with what works - that submit button. All I did was add an onclick attribute to the RBL to call a hidden button. Now you don't want to set the button to Visible=false because then the button won't appear in the generated markup. Instead, set the button's style to display:none; so that no one will see this hack, because yes, that's what this workaround is - it's a hack, but simple and just as effective as what you'd expect. Don't forget to remove the Autopostback="True" from your RBL.
CAVEAT: Because I'm using a hacked button for the onclick event, it's possible for the user to click in the area of the RBL, but not actually select an item. When this happens, our onclick triggers an AsyncPostBack and the codebehind logic will be processed, so please keep that in mind. To give you an idea of what I mean: all the Page_Load() events will be called, but rbl_Questions_SelectedIndexChanged() won't be if they happen to click in the area of the RBL without actually selecting an item. For my purposes this causes no issues in my logic and has no effect on the user.
Here's the Code:
Somewhere In the .Aspx Page:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:RadioButtonList ID="rbl_Questions" runat="server"
OnSelectedIndexChanged="rbl_Questions_SelectedIndexChanged">
</asp:RadioButtonList>
<asp:Button ID="btn_rbl_Questions" runat="server" style="display:none;"/>
<asp:Label ID="lbl_Result" runat="server" Text="" Visible="false">
</asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
In the Page_Load() event:
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack == false)
{
//Instead of using the AutoPostback of the RBL, use this instead.
rbl_Questions.Attributes.Add("onclick",
"document.getElementById('"
+ btn_rbl_Questions.ClientID
+ "').click();");
//Bind your RBL to a DataSource, add items programmatically,
// or add them in the aspx markup.
}
}
In the rbl_Questions_SelectedIndexChanged() event:
protected void rbl_Questions_SelectedIndexChanged(object sender, EventArgs e)
{
//Your code here.
//My code unhid the lbl_Result control and set its text value.
}

The above "hack" is no longer necessary (I am leaving it above since this was marked as the answer by the author). I have found the best way to do this, thanks to this SO Answer:
Updatepanel gives full postback instead of asyncpostback
The code is much simpler now, just remove what I put in the Page_Load() method and remove the Button I used in the Aspx page and add ClientIDMode="AutoID" and AutoPostBack="True" to the control you want the UpdatePanel to capture.
Somewhere In the .Aspx Page:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:RadioButtonList ID="rbl_Questions" runat="server"
ClientIDMode="AutoID" AutoPostBack="true"
OnSelectedIndexChanged="rbl_Questions_SelectedIndexChanged">
</asp:RadioButtonList>
<asp:Label ID="lbl_Result" runat="server" Text="" Visible="false">
</asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
MS changed how ClientID's are generated in .net 4.0 from "AutoID" to "Predictable" and I guess the ScriptManager or UpdatePanel's weren't updated correctly to use it. I can't find documentation on why that is anywhere or if it was left that way by design.
I seriously don't miss winforms.
Try this:
<asp:UpdatePanel runat="server" UpdateMode="Conditional" ID="pnlA">
You'll also need to setup
<Triggers>
//radio buttons
</Triggers>
Not sure how you'll do that since it's a dynamically built list.
I am using a ASP .NET ListView with a MS SQL Database. I use the ListView to show the information and in the list view, there is an hyperlink which opens the editing window for the specific record in a jQuery Modal Dialog Box.
<asp:ListView ID="ListView1" runat="server" DataSourceID="SqlDataSource1">
<LayoutTemplate>
<div id="itemPlaceholder" runat="server"> </div>
</LayoutTemplate>
<ItemTemplate>
<!--More Items -->
<a name="Link" href="EditItem.aspx?id=<%# Eval("articleid")%>">Edit</a>
<!--More Items -->
</ItemTemplate>
</asp:ListView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:myConnectionString %>"
SelectCommand="SQL-SELECT-STATEMENT">
</asp:SqlDataSource>
<div>
And jQuery works by taking the link of each item which has the name "Link" and associating it with a dialog box.
<script type="text/javascript">
$(document).ready(function() {
$("a[name=Link]").each(function() {
var $link = $(this);
var $dialog = $('<div></div>')
.load($link.attr('href'))
.dialog({
autoOpen: false,
title: "Edit Article",
width: 500,
height: 550
});
$link.click(function() {
$dialog.dialog('open');
return false;
});
});
});
</script>
Everything worked as it should. Earlier all the records could be shown in one go but as the number of records grew, I needed a paging solution. DataPager for the rescue!
<asp:DataPager ID="DataPager1" runat="server" PagedControlID="ListView1" PageSize="5">
<Fields>
<asp:NextPreviousPagerField />
<asp:NumericPagerField />
</Fields>
</asp:DataPager>
But now the DataPager's controls are not working! I cannot go back,forward or click a page number as it will open the first data bound item's href in the ListView without a dialog box (Just like a normal page). But if i remove the jQuery code, the paging works as it should but I don't get the neat modal dialog box for my editing :(
Any ideas why these cannot exist with each other? Thanx a lot in advance :)
UPDATE: What doesn't work is that they cannot co-exist peacefully. If i remove the jQuery code, the DataPager works fine but I will lost my modal dialog box for editing. If i put the jQuery code back, the modal dialog box works fine but the DataPager doesn't :(
My guess is that link selector is probably selecting data pager links.
You can try $("a[name='Link']").each(.. note single quotes around attribute value.
Alternately, why don't you use id or class selectors. For example:
<a id="editLink" ...
and
$('a#editLink;).each(...
I have a page with a listview that shows something like posts. On each post there should be a "rate box" which works similar to the "Like" button in facebook. The rate box is a User Control, that has an update panel inside it.
If I put the control with some random values in the page it works great - but when I put it inside the ListView, where it should be located, it won't work. The method is being called, but nothing happens.
I simplified the code a bit to make it easier to understand:
The "rate box" control:
protected void OnRateClick(object sender, ImageClickEventArgs e)
{
Rate++;
RateAmountLiteral.Text = Rate.ToString();
RateButton.Visible = false;
FeedbackLiteral.Visible = true;
rateButtonPanel.Update();
}
ascx:
<div class="rate_div">
<asp:UpdatePanel ID="rateButtonPanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<fieldset>
Rate:
<asp:Literal ID="RateAmountLiteral" runat="server"></asp:Literal>
<asp:ImageButton ID="RateButton" runat="server" ImageUrl="icn_rate.png"
OnClick="OnRateClick" />
<asp:Literal ID="FeedbackLiteral" runat="server" Visible="false">Thanks for rating!</asp:Literal>
</fieldset>
</ContentTemplate>
</asp:UpdatePanel>
</div>
aspx (using the control):
<asp:ListView ID="PostsView" runat="server" ItemPlaceholderID="itemPlaceHolder2"
<LayoutTemplate>
<div class="posts_div">
<asp:PlaceHolder ID="itemPlaceHolder2" runat="server" />
</div>
</LayoutTemplate>
<ItemTemplate>
<div class="post_div">
<div class="post_body">
<%# CurrentPost.Body %>
</div>
<UC:RatingBox id="RatingBox" runat="server"
PostID="<%# CurrentPost.ID %>"
Rate="<%# CurrentPost.Rate %>"/>
By: <a href="<%# CurrentPost.Author.LinkToProfile %>">
<%# CurrentPost.Author.DisplayName %>
</a> |
<%# CurrentPost.LiteralTime %>
</div>
</ItemTemplate>
</asp:ListView>
While debugging I noticed the controls in the method "OnRateClick" are empty and don't contain the right values. Please advice.
Also if you have any comments about the way I did things, don't hold yourself.
Thanks
There are a lot things that you may not have set up, I cannot tell from just the code snippet you have given. But make sure you do the following: -
1) Place a ScriptManager "" on the page.
If you are using master page in your application and your web page uses the master page, place script manager in master page. Or alternatively,you can also place script manager on specific web pages anyway.
2) Add a Triggers for the button RateButton in your Update panel.
I had a bunch of controls that I displayed, hid, enabled and disabled based on actions in the web page. Everything worked until i put them into an accordian. Now I can't get the Javascript to be able to update their state. I have a small example
this is the Javascript
<script type="text/javascript">
var ctrl = document.getElementById('<%= btmRocp.ClientID %>');
function ShowPanel(control)
{
alert('<%= btmRocp.ClientID %>');
ctrl.disabled = true;
}
</script>
This is the Accordian
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<cc1:Accordion ID="MyAccordion"
runat="Server"
SelectedIndex="0"
>
<Panes>
<cc1:AccordionPane ID="accordianPane0" runat=server>
<Header>Create New Report </Header>
<Content>a
<asp:Button ID="Button1" onmouseup="ShowPanel('') " runat="server" Text="Button" />
<asp:Button ID="btmRocp" runat="server" Text="Button" />
</Content>
</cc1:AccordionPane>
<cc1:AccordionPane ID="accordianPane1" runat=server>
<Header>Create New Report </Header>
<Content>b</Content>
</cc1:AccordionPane>
</Panes>
</cc1:Accordion>
I would love to know what i am doing wrong here the Alert prints out the right ID.
If i do something where i pass the "this" Object to the function i can disable that button but I truly need it to disable, or hide like 10 objects
Does anyone have an idea?
Sample Code at http://www.riconllc.com/accordian.zip
What is the default state of the Accordion? collapsed? I have no idea how the Accordion works, but I'm suspecting that it is modifying the HTML DOM such that when the page first loads "btmRocp" is not actually present on the page itself, until it becomes "visible". That is, it might be injecting controls into and out of the page, based on the accordion status.
Your best bet in figuring out this behavior is to insert "debugger;" statements into your page at appropriate points, to inspect the live DOM at those points in time.
<textbox id="debugbox" onblur="this.value = eval(this.value);"></textbox>
Is a good way to monkey with script on your page as well.
