Radiobutton in modalpopup causing postback even when inside UpdatePanel

Radiobutton in modalpopup causing postback even when inside UpdatePanel - c#

Posted is an abridged code of my user control. I have added an update panel over radio button and want to execute a server function which will toggle between consultant drop down list and reference name text box based on the selection without a full post back. But the radio button is causing a full postback. What am I doing wrong here?

instead of using updatepanel on modalpopup panel you can try something from code behind to serve the purpose.

Try setting the Enabled attribute in the RequiredFieldValidator element to "True".

.cs file:
protected void Page_Load(object sender, EventArgs e)
{
pnlMname.Visible = false;
}
protected void Button1_Click(object sender, EventArgs e)
{
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)

pnlname.Visible = true;
}
else if (DropDownList1.SelectedValue == "حقوقی")
{
pnlname.Visible = false;
pnlMname.Visible = true;
}
}

Try Like This:
Use your All code Inside Update Panels
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
// All Controls Placed Here
</ContentTemplate><Triggers>
</Triggers> </asp:UpdatePanel>
By default it will use Asynchronous postback

<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"
CausesValidation="false" />
When I select a date from the calender and press Search..The first time btnSearch_Click doesnt fire..If I click Search again it works fine. So I have to click the Search button twice before the click event works. This only happens if I select a date from the calender control.
Here is the full control:

Any Ideas?

You need to add ValidationGroup to your validation controls so that each validation group can perform validation independently from other validation group on a specific page. more you can read here Specifying Validation Groups
Here is your code with group validation. you can change it as your environment.

Hope this helps.

I don't know why but your problem can be solved by setting the CausesValidation property of btnSearch to true
<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"
CausesValidation="true" />
