The HyperLink under Panel within UpdatePanel is not clickable. When HyperLink is moved from sub panel to UpdatePanel, everything is good. Here is my code -
Page:
<asp:UpdatePanel ID="p" runat="server" RenderMode="Inline" UpdateMode="Conditional">
...
<some:UserControl ID="uc" runat="server" />
...
</asp:UpdatePanel>
SomeUserControl:
<asp:Panel ID="p" runat="server">
...
<asp:HyperLink ID="hlExportFile" runat="server" />
...
</asp:Panel>
Would be glad to hear any solution. Thanks ahead!
You Panel needs an ID.

In short: I want to enable a button i.e. outside UpdatePanel when I click on a button from inside UpdatePanel.
Problem: The button enables but tags i and asp:Localize are not showing in the rendered code after button click from UpdatePanel updPnlOfferings
Detail:
I have a DataList inside UpdatePanel which contains delete button for every item in the list. delete button is firing an event on server which deletes the record and disables a button (i.e. outside of the UpdatePanel.
As someone suggested I kept my button(which need to be disabled) in UpdatePanel below
<asp:UpdatePanel ID="updPnlCourse" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:LinkButton ID="lnkDeleteCourseDetails" runat="server" OnClick="lnkDeleteCourseDetails_Click">
<i class="icon-remove-sign"></i>
<asp:Localize ID="Localize6" runat="server" Text="<%$ Resources:CBLabels, LBL_DeleteDetails %>" />
</asp:LinkButton>
<asp:ConfirmButtonExtender ID="lnkDeleteCourseDetails_ConfirmButtonExtender" runat="server"
ConfirmText='Are you sure you want to delete this course?' Enabled="True" TargetControlID="lnkDeleteCourseDetails">
</asp:ConfirmButtonExtender>
</ContentTemplate>
</asp:UpdatePanel>
The Main UpdatePanel which is firing the event is below
<asp:UpdatePanel ID="updPnlOfferings" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Panel ID="pnlDSOfferings" runat="server">
<asp:DataList ID="dtlstOfferings" runat="server" OnItemCommand="dtlstOfferings_ItemCommand" EnableViewState="true">
</asp:DataList></asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
on dtlstOfferings_ItemCommand event I coded this
lnkDeleteCourseDetails.Enabled = true;
lnkDeleteCourseDetails.ToolTip = "";
lnkDeleteCourseDetails_ConfirmButtonExtender.Enabled = true;
updPnlCourse.Update();
This is a known problem as specified in this link.
The solution is to put all your content that are there inside the LinkButton, within a place holder like below, or make all the child controls as server controls.
<asp:LinkButton ID="lnkDeleteCourseDetails" runat="server" OnClick="lnkDeleteCourseDetails_Click">
<asp:PlaceHolder runat="server">
<i class="icon-remove-sign"></i>
<asp:Localize ID="Localize6" runat="server" Text="<%$ Resources:CBLabels, LBL_DeleteDetails %>" />
</asp:PlaceHolder>
</asp:LinkButton>
So I have this Checkboxlist and I want to implement a Select All feature for the elements inside it. I placed it inside an UpdatePanel, but everytime I click an item, the entire page is reloaded. This is my code:
<asp:UpdatePanel ID="CBLPanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">
<ContentTemplate>
<div class="LeftAligned">
<asp:Label ID="FilterLabel" runat="server" Text="Filter by:" />
<asp:DropDownList runat="server" ID="FilterDDL" AutoPostBack="true" OnSelectedIndexChanged="FilterDDL_SelectedIndexChanged" />
<asp:ImageButton ID="FB" runat="server" ImageUrl="~/images/filter.png" AlternateText="VALUE"
CssClass="filter_button" OnClick="FB_Click" />
<div onmouseout="javascript:bMouseOver=false;" onmouseover="javascript:bMouseOver=true;"
class="filter_div">
<asp:CheckBoxList AutoPostBack="true" ID="FilterCheckBoxList" ClientIDMode="Static"
runat="server" CssClass="filter_checklist collapsed" OnSelectedIndexChanged="FilterCheckBoxList_Selected">
</asp:CheckBoxList>
</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
I though I should set ChildrenAsTriggers to false and this way I would update only from the code, but it doesn't seem to work.
This looks like a familiar .NET Bug. Setting ClientIDMode=Auto on the CheckBoxList should fix it
Im trying tp upload more than one image, and when each one I upload I will show it in a repeater, but in the code behind the FileUpload1.HasFile is always False , this is a piece of my code :
<asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional" >
<ContentTemplate>
<asp:Repeater ID="rpUploadedImages" runat="server">
<ItemTemplate>
<img src='../Images/<%# DataBinder.Eval(Container.DataItem, "ImagePath")%>'/><br />
</ItemTemplate>
</asp:Repeater>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnupload" EventName="click" />
</Triggers>
</asp:UpdatePanel>
<asp:FileUpload ID="FileUpload1" runat="server" /><br />
<asp:Button ID="btnupload" runat="server" Text="Upload" onclick="btnupload_Click" />
The FileUpload control does not work with UpdatePanel, you will need to do a full post back to get the file on the server... Now there are a lot of tricks to make it ajaxy...
http://geekswithblogs.net/ranganh/archive/2008/04/01/file-upload-in-updatepanel-asp.net-ajax.aspx
Another tricky way is to create iframe with fileupload + submit button(or some trigger) inside your main form. iframe will postback with no effect to main page.
i'm kinda new in web programming,
i'm trying to design a search page.
i want to creating few radio buttons where each click on a radio button will show a div
contains the related search div's.
and from there to do the query to the database(not related to the post)
how can i do that ?
tried to search for it , and didn't get good answer.
i want that the change of the page will be in server side and not the client side.
p.s.
i have been working with ajax control kit so far..
thanks for the help.
You just need an UpdatePanel, radio buttons and a MultiView control.
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div>
<asp:RadioButton ...
<asp:RadioButton ...
</div>
<asp:MultiView ID="mvAll" runat="server" ActiveViewIndex="-1">
<asp:View ID="vwFirst" runat="server">
</asp:View>
<asp:View ID="vwSecond" runat="server">
</asp:View>
...
</asp:MultiView>
</ContentTemplate>
</asp:UpdatePanel>
When the selected radio button changed you just set the View related to be active,
mvAll.SetActiveView(ViewIDYouNeed);
You can accomplish this with Panels and an Update Panel.
<asp:RadioButton ID="rdo1" AutoPostBack="true" GroupName="radios" runat="server" OnCheckedChanged="ShowDivs" />
<asp:RadioButton ID="rdo2" AutoPostBack="true" GroupName="radio2" runat="server" OnCheckedChanged="ShowDivs" />
<asp:UpdatePanel runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Panel ID="pnl1" runat="server" Visible="false"></asp:Panel>
<asp:Panel ID="pnl2" runat="server" Visible="false"></asp:Panel>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="rdo1" />
<asp:AsyncPostBackTrigger ControlID="rdo2" />
</Triggers>
</asp:UpdatePanel>
You would then handle setting the Visible property of the panels in your ShowDivs method in your code behind.
Or, you could use jquery/javascript to accomplish this.
<input type="radio" onClick="ShowDiv(1)" />
function ShowDiv(id) {
HideDivs();
$(id).show('slow');
}
I have a modalpopupExtender which is opened when edit button is clicked.In that i have a gridview in which if click any row the popup gets hidden and the values are displayed on the page.The problem is that when i keep this code in the update panel the modalpopupextender is not getting hidden after clicking in the gridview.I have a master page in my page and using Ajax modal popup extender
are you doing a full postback? If so, in the Click event why not use ModalPopup.Hide()??
I saw the same behavior what i did was putting modelpopup before update panel that way it worked
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<cc1:ModalPopupExtender ID="mpeScreenFreez"
runat="server"
BackgroundCssClass="modalBackground"
DropShadow="true"
TargetControlID="btnDummy"
PopupControlID="panFreeze">
</cc1:ModalPopupExtender>
<asp:Panel ID="panFreeze" runat="server" CssClass="modalPopup" style="display:none;">
<asp:Label ID="lblSave" runat="server" Font-Bold="true" Text="Sending the Quote....">
</asp:Label>
</asp:Panel>
<asp:Button ID="btnDummy" runat="server" CssClass="hidden" />
<asp:UpdatePanel ID="upDirectHomOwnrPremQuote" runat="server">
