Inside form view I have drop down list on selected index change I have text box appearing.
Now I want to keep both these drop down and Text box inside Ajax update panel. Upon click button out side update panel I want to save these two fields as well.
Any help Much appreciated.
Here aspx code
<asp:TextBox ID="NameTextBox" runat="server" Text='<%# Bind("Name") %>' />
<br />
<asp:DropDownList ID="ddlLName"
runat="server" ValidationGroup="VG1" SelectedValue='<%# Bind("LNAMEIFYES") %>' OnSelectedIndexChanged="ddlLName_SelectedIndexChanged" AutoPostBack="True">
<asp:ListItem Value="">Please select...</asp:ListItem>
<asp:ListItem Value="1">Yes</asp:ListItem>
<asp:ListItem Value="2">No</asp:ListItem>
</asp:DropDownList>
<br />
<asp:Panel ID="pnlLNAme" runat="server" Visible="false">
LName:
<asp:TextBox ID="LNameTextBox" runat="server" Text='<%# Bind("LName") %>' />
<br />
</asp:Panel>
Code Behind
protected void ddlLName_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList ddlLName = (DropDownList)FormView1.FindControl("ddlLName");
if (ddlLName.SelectedValue == "1")
{
Panel pnlLNAme = (Panel)FormView1.FindControl("pnlLNAme");
pnlLNAme.Visible = true;
}
else
{
Panel pnlLNAme = (Panel)FormView1.FindControl("pnlLNAme");
pnlLNAme.Visible = false;
}
}
I solved the problem by using by using two update panals, using trigger in one of the update panal.

I have two section of elements inside the form (e.g. pizza and burger).
Each section has different fields and each section has its own submit button.
Now I want to validate each of these section only if their corresponding submit button is pressed. If the other submit button is pressed, it should not validate other section of elements.

You need to use Validation Groups, from MSDN -
Validation groups allow you to organize validation controls on a page
as a set. Each validation group can perform validation independently
from other validation groups on the page.
For example (from MSDN):
<asp:requiredfieldvalidator id="RequiredFieldValidator2"
controltovalidate="AgeTextBox"
validationgroup="PersonalInfoGroup"
errormessage="Enter your age."
runat="Server">
</asp:requiredfieldvalidator>
<!--When Button1 is clicked, only validation controls that are a part of PersonalInfoGroup
are validated.-->
<asp:button id="Button1"
text="Validate"
causesvalidation="true"
validationgroup="PersonalInfoGroup"
runat="Server" />
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">

<asp:DropDownList runat="server" ID="cmbSnippet" CssClass="dropdown" AutoPostBack="true">
<asp:ListItem>
None
</asp:ListItem>
<asp:ListItem>

</asp:ListItem>
<asp:ListItem>
Read Feed
</asp:ListItem>
</asp:DropDownList>
</p>
<!--Code-->
<p>
<asp:Label runat="server" ID="lblCode" AssociatedControlID="txtCode">
From code:
</asp:Label>
<asp:TextBox runat="server" ID="txtCode" TextMode="MultiLine" CssClass="editor" MaxLength="100" Height="200" Wrap="false" />
</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'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'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....
