I've got a table which i want to update with a button, the table is within a "li" tag, and the button is in another. Here's my code:
<li runat="server">
<asp:DropDownList ID="cYear" runat="server" Width="100%" Font-Size="Large">
<asp:ListItem>2011</asp:ListItem>
...
</asp:DropDownList>
<asp:DropDownList ID="cMonth" runat="server" Width="100%" Font-Size="Large">
<asp:ListItem>1</asp:ListItem>
...
</asp:DropDownList>
<asp:DropDownList ID="cDay" runat="server" Width="100%" Font-Size="Large">
<asp:ListItem>1</asp:ListItem>
...
</asp:DropDownList>
<asp:TextBox ID="cNum" runat="server"></asp:TextBox>
<asp:Button ID="cEvent" onclick="cEvent_Click" CausesValidation="false"/>
</li>
<li runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel id = "updatePanel1" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="cEvent"/>
</Triggers>
<ContentTemplate>
...
</ContentTemplate>
</asp:UpdatePanel>
</li>
The Site is in Hebew so just ignore the wired string, the button Id is cEvent, and i want it to update the updatePanel, but instead it just doing nothing....

I tried to populate dropdown city and area without page refresing. So i used in Updatepanel and Script Manager.The code is below
<asp:ScriptManager ID="script1" runat="server" EnablePartialRendering="true"></asp:ScriptManager>
<div class="form-list wow fadeInRight" data-wow-delay="0.5s">
<ul class="navmain">
<li>
<asp:UpdatePanel ID="upd1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
<ContentTemplate>
<!--<asp:DropDownList ID="drp_city" runat="server" CssClass="drp" OnSelectedIndexChanged="drp_city_SelectedIndexChanged" AutoPostBack="true" ></asp:DropDownList>-->
<asp:DropDownList ID="drp_city1" runat="server" CssClass="drp" OnSelectedIndexChanged="drp_city_SelectedIndexChanged" AutoPostBack="true"></asp:DropDownList>
<asp:HiddenField ID="hfCustomerId" runat="server" />
</ContentTemplate>
</asp:UpdatePanel>
</li>
<li>
<asp:UpdatePanel ID="upd2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drp_area" runat="server" CssClass="drp" AutoPostBack="true"></asp:DropDownList>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="drp_city1" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
</li>
<li>
<asp:UpdatePanel ID="upd3" runat="server">
<ContentTemplate>
<asp:DropDownList ID="drp_cuisine" runat="server" CssClass="drp"></asp:DropDownList>
</ContentTemplate>
</asp:UpdatePanel>
</li>
</ul>
<asp:Button OnClick="btn_search1" runat="server" CssClass="btn_search" />
</div>
I can't find the error. Page is not refreshing but area dropdown is not populating.
I've two updatePanel :
the first :
<asp:Panel ID="pnlConso" runat="server" Height="500px" ScrollBars="Auto">
<asp:UpdatePanel ID="upConsommateur" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="tbLogin" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="btnValiderAjout" EventName="Click" />
</Triggers>
<ContentTemplate>
...
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
and the second :
<asp:UpdatePanel ID="upAjoutConso" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Panel ID="pnlAjoutConsommateur" runat="server" CssClass="invisible">
<table>
...
<tr>
<td>
<asp:Button ID="btnValiderAjout" runat="server" Text="Valider" CssClass="invisible" />
</td>
</tr>
</table>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
then my problem is when I click on the btnValiderAjout the first panel don't update.
I make this button such as a trigger for the first but it don't update ... What I'm doing wrong ?
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>

</asp:ListItem>
<asp:ListItem>

<asp:ListItem>

<asp:Asyncpostbacktrigger controlid="cmbSnippet" eventname="SelectedIndexChanged" />

</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'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.

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
