I'm trying to use a modal popup extender on my page so when I click a button, it must show a panel. Here is what I have:
<asp:UpdatePanel runat="server" ID="updPanel">
<ContentTemplate>
<ajaxToolkit:ModalPopupExtender ID="mpeEmailComplete" runat="server" TargetControlID="btnTesting"
PopupControlID="pnl" OkControlID="btnOk"
BackgroundCssClass="modalBackground">
</ajaxToolkit:ModalPopupExtender>
<asp:Panel ID="pnl" runat="server" style="display:none;">
<asp:UpdatePanel ID="udp" runat="server">
<ContentTemplate>
<asp:Panel runat="server" ID="pnlEmailComplete" Visible="false">
<asp:Label runat="server" ID="lblTest" Text="Testing testing testing"></asp:Label>
<asp:Button runat="server" ID="btnOk" Text="OK" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
<asp:Button runat="server" ID="btnTesting" Text="Testing"/>
</ContentTemplate>
</asp:UpdatePanel>
but i can't get the panel to popup when the button is clicked. Anybody know why?
Your innermost panel has Visible=false.
<asp:Panel runat="server" ID="pnlEmailComplete" Visible="false"> *(change here)*
So, when you press the TESTING button, the ModalPopupExtender correctly causes the outer panel to display, but it's displaying an invisible inner panel, hence you see nothing on screen.
<asp:Panel ID="pnl" runat="server" style="display:none;"> *(this is ok)*
To fix, just yank the Visible=false from the outer panel (pnlEmailComplete)
Hope that helps!
Do you have any JavaScript errors and is pnl.Visible=False; set on the server-side anywhere?
Make sure you have the AjaxControlToolkit referenced properly, NuGet is the easiest way to add the reference.

<asp:Button ID="Btnshow" runat="server" Text="Show" OnClick="Btnshow_Click" />

Does anyone know what could be causing it? Thanks
I am trying to learn how to use UpdatePanel And this is my code.The problem is everything is ok but I cant see Loading.gif image .when code excatues Its wisible aspx page .What am i missing out here
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate>
<img src="load.gif" />
</ProgressTemplate>
</asp:UpdateProgress>
</div>
You should have trigger in UpdatePanel like this:
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
</Triggers>
Try to use asp:Image:
<ProgressTemplate>
<asp:Image ID="loader" runat="server" ImageUrl="~/img/loader.gif" />
</ProgressTemplate>
I am not understanding why this doesn't fire. It will not even call the event. Any thoughts? Really what I want to do, is prevent a full post-back. The page is large and each time it does a post back it jumps to the top.
<asp:UpdatePanel runat="server" id="UpdatePanel" updatemode="Conditional">
<ContentTemplate>
<p>
<asp:Label runat="server" ID="lblSnippet" AssociatedControlID="cmbSnippet">
From snippet:
</asp:Label>
<asp:DropDownList runat="server" ID="cmbSnippet" CssClass="dropdown" AutoPostBack="true">
<asp:ListItem>

</p>
</ContentTemplate>
<Triggers>
<asp:Asyncpostbacktrigger controlid="cmbSnippet" eventname="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
you have not declared the event
something like this:
<asp:DropDownList runat="server" ID="cmbSnippet" CssClass="dropdown" AutoPostBack="true" OnSelectedIndexChanged="cmbSnippet_SelectedIndexChanged">
and his relative handler in codebehind...
I have an autocompleteextender that displays the list of countries. In the same textbox, when I type something and click on "Search" button, a pop-up should be opened and should display the matching countries. I am using modalpopupextender for the popup.
aspx code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<contenttemplate>
<asp:TextBox id="TextBox1" runat="server" Width="250px"></asp:TextBox>
<asp:ImageButton id="ImageButton1" onclick="imgBtnSearch_Click" runat="server" ImageUrl="~/Images/Lab/search.jpg"></asp:ImageButton>
<cc1:AutoCompleteExtender id="TextBox1_AutoCompleteExtender" runat="server" EnableCaching="true" CompletionSetCount="10" MinimumPrefixLength="1" ServicePath="AutoComplete.asmx" UseContextKey="True" TargetControlID="TextBox1" ServiceMethod="GetCountryInfo">
</cc1:AutoCompleteExtender>
<cc1:ModalPopupExtender id="ModalPopupExtender1" runat="server" TargetControlID="ImageButton1" BackgroundCssClass="ModalPopupBG" Drag="true" PopupDragHandleControlID="PopupHeader" PopupControlID="updatePanel2" CancelControlID="btnCancel" ></cc1:ModalPopupExtender>
</contenttemplate>
</asp:UpdatePanel>
<asp:UpdatePanel id="updatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:RadioButtonList id="RadioButtonList1" runat="server" Width="400" Height="400" RepeatColumns="5" RepeatLayout="Table" RepeatDirection="Vertical" AutoPostBack="True"></asp:RadioButtonList>
<DIV class="Controls">
<INPUT id="btnOk" type="button" value="OK" />
<INPUT id="btnCancel" type="button" value="Cancel" />
</DIV>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ImageButton1" EventName="Click"></asp:AsyncPostBackTrigger>
</Triggers>
</asp:UpdatePanel>
And in my codebehind:
protected void imgBtnSearch_Click(object sender, ImageClickEventArgs e)
{
LoadCountryPopUp();
ModalPopupExtender1.Show();
}
I am not getting any countries in my popup, although I get results via my autocompleteextender. On clicking the imagebutton, I get the popup without any content. Pls help!
Place your popup contents inside panel like this:
<asp:UpdatePanel id="updatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Panel id="pnlPopup" runat="server">
<asp:RadioButtonList id="RadioButtonList1" runat="server" Width="400" Height="400" RepeatColumns="5" RepeatLayout="Table" RepeatDirection="Vertical" AutoPostBack="True"></asp:RadioButtonList>
<DIV class="Controls">
<INPUT id="btnOk" type="button" value="OK" />
<INPUT id="btnCancel" type="button" value="Cancel" />
</DIV>
</Panel>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ImageButton1" EventName="Click"></asp:AsyncPostBackTrigger>
</Triggers>
</asp:UpdatePanel>
and replace UpdatePanel's controls Id with this Panel's id:
<cc1:ModalPopupExtender id="ModalPopupExtender1" runat="server" TargetControlID="ImageButton1" BackgroundCssClass="ModalPopupBG" Drag="true" PopupDragHandleControlID="PopupHeader" PopupControlID="pnlPopup" CancelControlID="btnCancel" ></cc1:ModalPopupExtender>
and check if it works?
Try putting the extenders outside of the update panel, it should not be a child of what it is extending
Here is my code:
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" ChildrenAsTriggers="false" runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" Text="Click1" OnClick="Button1_Click" />
<br />
<br />
Last refresh
<%=DateTime.Now.ToString() %>
<br />
<br />
<asp:UpdatePanel ID="UpdatePanel2" UpdateMode="Conditional" ChildrenAsTriggers="true" runat="server">
<ContentTemplate>
<asp:Button ID="Button2" runat="server" Text="Click2" OnClick="Button2_Click" />
<br />
<br />
Last refresh
<%=DateTime.Now.ToString() %>
<br />
<br />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button2" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</div>
</form>
</body>
Im using two update panels here, when i click "Button2" then "UpdatePanel2" was refreshed, if i click "Button1" then both update panel were refreshed, but my need is if i click "Button1" then "UpdatePanel1" have to be refreshed.
Thanks.
This behavior is by design. Because your UpdatePanel2 is nested inside of UpdatePanel1, when you refresh the contents of UpdatePanel1, this includes the child UpdatePanel.
If you want UpdatePanel2 to act separately from UpdatePanel1, you're going to have to take it out of UpdatePanel1 and make it a sibling, rather than a child.
