Modelpopup extender in asp .net issue - asp.net

I have successfully added controls to pop up, like many check boxes ... now on check box checked event I want to show another check boxes on same popup. how can I do that plz can any one help me?

Make sure autopostback is true and wrap them in an updatepanel inside of the modal. Now you will be able to show/hide whatever you want on postback without the modal closing.

Do you want to just display check boxes(that's hidden) on checked event of other checkbox? You can attach javascript function to onClick event of check box and you can set visibility of other check boxes.
If you want to handle that in server side, you need to set autopostback to true and specify OnCheckedChanged event.
<asp:CheckBox AutoPostBack="true" runat="server" ID="chk1" OnCheckedChanged="chk1_OnCheckedChanged" />
protected void chk1_OnCheckedChanged(object sender, EventArgs e)
{
}
And put the modal popup control inside the update panel.
<ajaxtoolkit:modalpopupextender runat="server" ID="mpe"
BehaviorID="mpe_ID" PopupControlID="pnlModalPopup"
TargetControlID="btnSomething" CancelControlID="lnkUploadSongListOverlayClose"
DropShadow="false" />
<asp:Panel runat="server" ID="pnlModalPopup" CssClass="modal">
<asp:UpdatePanel runat="server" ID="updatePanel">
<ContentTemplate>
<!-- modal popup control -->
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>

Here are the steps:
1- Set autopost back for the checkbox to true
2- Double click on the checkbox and on the checkbox1_OnCheckedChanged
if(checkbox1.Checked==true){Modalpopupextender.show();}

ASP.Net and postback

I have a form for people to put in info on my contact page. I'm trying to figure out how once they click submit to NOT show the form anymore and show a simple thankyou.
Thank You
Create a multiview control with 2 views.Place all your controls into one and a "thank you" message in the other and toggle the ActiveViewIndex on submit click
The simplest way would just be to use Panel controls:
<asp:Panel ID="pnlForm" runat="server">
... form here ...
<asp:Button ID="btnSubmit" OnClick="btnSubmit_Click" Text="Submit" runat="server" />
</asp:Panel>
<asp:Panel ID="pnlThankYou" Visible="False" runat="server">
Thanks!
</asp:Panel>
C#
protected void btnSubmit_Click(object sender, EventArgs e)
{
pnlForm.Visible = false;
pnlThankYou.Visible = true;
}
Try to put both sections in separate divs and make divs runat=server
and set the div which not required visible to false or just add attribute display to hide at server side
and show the other div by visible true or by attribute to block

how to set a default 'enter' on a certain button

There is a textbox on a ContentPage. When the user presses Enter in that textbox I am trying to fire a 'Submit' button on this ContentPage. I'd like to fire off that particular button's event.
Instead, there is a search textbox & button on the top of the page from a MasterPage, and this search button's event fires off.
How do I control to fire off this ContentPage's submit button, instead of the MasterPage's search button?
I am using Ektron CMS for my content management.
The easiest way is to put the fields and button inside of a Panel and set the default button to the button you want to be activated on enter.
<asp:Panel ID="p" runat="server" DefaultButton="myButton">
<%-- Text boxes here --%>
<asp:Button ID="myButton" runat="server" />
</asp:Panel>
if you need to do it from code, use
Me.Form.DefaultButton = Me.btn.UniqueID
Where btn is your button control.
You can use the DefaultButton property on either a server-side form control or Panel control. In your case, group the controls together in a Panel that should fire off the same button:
<asp:Panel ID="SearchBox" runat="server" DefaultButton="BtnSearch">
...
<asp:Button ID="BtnSearch" runat="server" Text="Search!" />
</asp:Panel>
....
<asp:Panel ID="UserPanel" runat="server" DefaultButton="BtnUserSubmit">
...
<asp:Button ID="BtnUserSubmit" runat="server" Text="Submit" />
</asp:Panel>
You can now use UseSubmitBehavior property to disable all the buttons you don't want to fire when hitting submit (check out the documentation for more info)
<asp:Button ID="BtnNotToFIre" runat="server" Text="Search" UseSubmitBehavior="false" />
Microsoft say:
<form id="Form1"
defaultbutton="SubmitButton"
defaultfocus="TextBox1"
runat="server">
enter link description here
$(document).ready(function(){
document.getElementById("text_box_id")
.addEventListener("keyup", function(event) {
event.preventDefault();
if (event.keyCode === 13) {
document.getElementById("button_id").click();
}
});
});

How to refresh an opened popup extender panel

I have a gridview where I have button for each row. After clicking this button, the Modal PopUp Extender Panel is opened (with PanelName.Show()). The Panel contains a user control, which shows some labels, textboxes,etc. with an additional info binded form SqlDataSource. Until this point it works well. But, when I click another button, the panel is purely shown but the content is not refreshed (based on which button is clicked, some details info should be shown). Basically, the method SqlDataSource_Selecting is called only for the panel popup showing but not anymore.
How can I force panel to be refreshed (reloaded) after each PanelName.Show()??
Thanks in advance.
If I'm understanding your question correctly, I think the problem is that you just need to re-Bind your data bound controls after the user clicks the button to change the Selected item. You can use [ControlName].DataBind() to do that. Does that make sense?
It depends on whether the control(s) you want to refresh are DataBound() or not.
In other words, can you force the control to reload by using a DataBind() method call to force the control to reload itself, with either the same or new data?
Most GUI controls have the DataBind() method, but it's useless if the control is not actually using data to work!
This is why in your case your panel is not "refreshed" with new data because using a DataBind() on the panel does nothing. Using a databind() on the entire GridView is a different story and should work. Maybe place an UPDATEPANEL around the whole lot? If you do you have to be careful your normal edits and other Commands on the rows will continue to work.
However, What you can do is place the modalpopupextender inside your TemplateField, and using a "trick", you can keep your server post backs and still fire the popup panel.
ie
<asp:UpdatePanel ID="upADDMAIN" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Button ID="btnADD" runat="server" Text="NEW LOGIN" BackColor="Blue" Font-Bold="True" ForeColor="#FFFFCC" OnClick="btnADD_Click" />
<asp:Button ID="btnDUM" runat="server" style="display:none" />
<div style="height:20px">
</div>
<ajaxToolkit:ModalPopupExtender ID="mpeADD" runat="server"
targetcontrolid="btnDUM"
popupcontrolid="upADD"
backgroundcssclass="modelbackground">
</ajaxToolkit:ModalPopupExtender>
<asp:UpdatePanel ID="upAdd" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Panel ID="pnlADD" runat="server" Width="700px" HorizontalAlign="Center" CssClass="auto-style10" Height="200px">
..
..
<div id="puFTR" class="auto-style17" style="vertical-align: middle">
<asp:Button id="btnOK" runat="server" Text="OK" style="width: 80px" OnClick="btnOK_Click" />
<asp:Button id="btnCAN" runat="server" Text="CANCEL" style="width: 80px" OnClick="btnCAN_Click" CausesValidation="False" />
</div>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
</ContentTemplate>
</asp:UpdatePanel>
As you may see, the btnDUM control is a Dummy to get the MPE to work, but it's not actually used as it's hidden by the style="display:none" tag.
However, the btnADD does work because it calls a Click() method on the server side which does the refresh of data on your new row. You may have to use a little jScript to pass the ROWINDEX into the Click() method for it to work with a GridView.
Incidentally, the Click() method in my case "controls" the MPE manually...
protected void btnADD_Click(object sender, EventArgs e)
{
ClearADDform();
mpeADD.Show();
}
protected void ClearADDform()
{
txtLOGIN.Text = string.Empty;
cbISActive.Checked = true;
txtPWD.Text = string.Empty;
ddlAgent.SelectedIndex = -1;
}
In my case, the above code example is outside a GridView, so you'll need to adjust.
But the point is, you can still have Server Side calls using Ajax popups!
Good luck.

jQuery click disappears into some abyss

Here is my setup:
I have an asp.net button on a page --
<asp:Button id="btnSelectEmp" runat="server" Text="Select Employee" />
I have a .js file with the following jQuery click event --
$("input[id$='_btnSelectEmp']").click(function ($e) {
$("div[id$='_divEmpSearch']").css("display", "inline");
$e.preventDefault();
});
As you can see, clicking upon the button will set a div visible. Nothing special; not rocket science.
The div is wrapped with an asp.net update panel, and it contains an asp.net user control (.ascx)
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div id="divEmpSearch" runat="server" style="display: none;">
<uc:EmpSearch ID="ucEmpSearch" runat="server" />
</div>
// And a bunch of other controls that are updated according to whatever the user selects in the user control above
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ucEmpSearch" />
</Triggers>
</asp:UpdatePanel>
The user control above is also wrapped in an asp.net update panel, because it has to communicate with the server. Among other controls like textboxes and such, the user control has two buttons upon it: 1) an asp.net button that does a postback and 2) an asp.net button that does an asynchronous postback.
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click" /
<br />
asp:Button ID="btnContinue" runat="server" Text="Select" OnClick="btnContinue_Click" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSearch" EventName="Click" />
<asp:PostBackTrigger ControlID="btnContinue" />
</Triggers>
</asp:UpdatePanel>
The button in the user control that does a postback is working great. I click it, a postback occurs and my div control is re-hidden. I can then click on the Select Employee button (the one that I supplied the code for at the very first of the question) and the jQuery click event is handled and the div will be reshown.
However, the button in the user control that does an asynchronous postback works also, but after it hides the div, if I then click on the Select Employee button the jQuery click event will not be handled.
What this tells me is that for some reason during an asynchronous postback to the page, something happens to the Select Employee button so that the jQuery click event no longer happens. Why?
Your button is replaced with a new one when your update panel comes back with new content, so this:
$("input[id$='_btnSelectEmp']").click(function ($e) {
Binds to the elements it finds at that time, instead you'll want .delegate() or .live() here to listen for click events from current and future elements, like this:
$("input[id$='_btnSelectEmp']").live("click", function ($e) {
$("div[id$='_divEmpSearch']").css("display", "inline");
$e.preventDefault();
});
Or a bit cheaper using .delegate():
$("#container").delegate("input[id$='_btnSelectEmp']", "click", function ($e) {
$("div[id$='_divEmpSearch']").css("display", "inline");
$e.preventDefault();
});
In this case #container should be a parent of the update panel, one that doesn't get replaced in the postback.
Use the live() function. live() delegates the click event to a parent element, so the element (in this case btnSelectEmp) doesn't need to exist at the time the event is bound.
$("#<%=btnSelectEmp.ClientID%>").live("click" function ($e) {
$("#<%=divEmpSearch.ClientID%>").css("display", "inline");
$e.preventDefault();
});
What is happening is the btnSelectEmp button is getting replaced by the asynchronous call and the new element has not been bound to an event handler.
Also, I've modified the jquery selector here to use the exact client id of the element. This will improve speed, plus I seem to recall certain selectors don't work with event delegation in certain versions of Jquery.
try live('click', function(){...}) instead of click(function(){...})
Wild guess : "_btnSelectEmp" is used more than once?

AJAX TabContainer containing user controls

Wondering if someone here can help.
I have an AJAX tabcontainer which has a number of tabs and each tab contains a user control. When I add a new item from one of the tabs, it is not reflected in the user control in another tab unless a postback occurs. (e.g. the first tab has a listview where I add a new record and the second has a simple form which contains a drop-down which I expect to contain value added from first tab).
How can I make the tabcontainer to refresh its tabs from a usercontrol?
Any help will be most appreciated.
Thanks,
Ali
You could fire an event from your first user control so that the page can handle this event and tell the other usercontrol to databind
Here is a example
<act:TabContainer ID="TabContainer2" runat="server" CssClass="EmployeeProfile" ActiveTabIndex="0">
<act:TabPanel ID="TabPanel1" runat="server" HeaderText="Datos Generales">
<ContentTemplate>
<br />
<uc1:EmployeeGeneralDetails ID="EmployeeGeneralDetails2" runat="server" OnUpdated="EmployeeGeneralDetails2_OnUpdated" />
</ContentTemplate>
</act:TabPanel>
<act:TabPanel ID="TabPanel2" runat="server" HeaderText="Referenias Personales">
<ContentTemplate>
<uc3:EmployeeResumeView ID="EmployeeResumeView2" runat="server" />
</ContentTemplate>
</act:TabPanel>
</act:TabPanel>
protected void EmployeeGeneralDetails2_OnUpdated(object o, EventArgs e)
{
EmployeeResumeView2.DataBind();
}
