Hi,

I am using a RadButton in one of my aspx pages but on clicking the button, the click event is not firing.
Here is the Markup of my page.

<asp:Label ID="labelCard" runat="server" Text="Select Card Type"></asp:Label>
<asp:DropDownList ID="ddlType" runat="server" AutoPostBack="true" DataTextField='<%# Eval("Type") %>' Width="120px">
    <asp:ListItem>--Select--</asp:ListItem>
    <asp:ListItem>Type 1</asp:ListItem>  
    <asp:ListItem>Type 2</asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator ID="RequiredCardValidator1" runat="server" ErrorMessage="Please select card type" ControlToValidate="ddlType" InitialValue="--Select--" />
<asp:Label ID="labelCode" runat="server" Text="Enter Coupon Code"></asp:Label>
<asp:TextBox ID="textCode" runat="server" />
<asp:RequiredFieldValidator ID="RequiredNameValidator2" runat="server" ErrorMessage="Please enter coupon code" ControlToValidate="textCode" Display="Dynamic" />
<telerik:RadButton ID="btnCheck" runat="server" Text="Submit" OnClick="btnCheck_Click">
</telerik:RadButton>

Thanks,
Ben

Hi,

Most probably the button postback is not happening because of a validation control on the page, containing the RadButton. There are certain cases in which the validation requirements are not met and the RadButton doesn’t initiate postback, which may cause confusion if the validation is not easy to spot and the button is not supposed to be part of it.

If you want to exclude the RadButton from the validation mechanism of the page, you can set its CausesValidation property to false (this is also valid for a regular asp Button control).

ASPX:

<telerik:RadButton ID="btnCheck" runat="server" Text="Submit" CausesValidation="false" OnClick="btnCheck_Click">
</telerik:RadButton>

Thanks,
Princy,

Assuming that my problem with a RadButton is due to this, is there any way to force the validator that is causing the issue to be more visible / raise an alert or whatever?  If it is in fact failing validation, it would be nice to know when and why....

Hi Allen,

The faced issue s usually caused by the Unobtrusive validation of .NET 4.5. Although it cannot be made more visible (in terms of error messages), you can disable it by adding the following lines in the web.config:

    <appSettings>
        <add key="ValidationSettings:UnobtrusiveValidationMode" value="None"/>

I am having the same problem.  I have aspx page with simple radbuttons on them.  Yesterday when testing they all worked fine. Today the code behind does not fire (I put breakpoint there - it never hits).  I added your CausesValidation = false clause to all buttons but it makes no difference. It is just this one page.  All other buttons on all other pages work fine.  Checkboxes and textboxes still work on this page.  Just the radbuttons suddenly stopped working

Hi David,

To troubleshoot the issue with your RadButtons not firing their click events, consider the following possibilities:

Page Validation: Is there any validation control on your page that might be preventing the postback? You've set CausesValidation to false, but ensure that there are no other validation controls interfering.

JavaScript Errors: Are there any JavaScript errors on the page? Sometimes, JavaScript errors can prevent postback. Use the browser's developer tools to check for errors.

Event Handler Binding: Are the click event handlers properly bound to the RadButtons? If you've changed any code or renamed buttons, ensure that the event handlers are correctly associated.

Browser Caching: Could browser caching be an issue? Sometimes, browsers cache pages and don't reflect recent changes. Try clearing the cache or testing in a different browser.

Incognito mode: Test in incognito mode to see if the issue is not due to some plugin.

ASP.NET AJAX UpdatePanel: If your buttons are inside an UpdatePanel, ensure that the panel is refreshing as expected.

Web.config Settings: Check your web.config for any settings that might affect button behavior, such as unobtrusive validation settings.

Code Behind: Are there any changes in the code-behind file that might affect the event triggering?

Simplify the problematic page: Reduce the components on the page until you find the reason for the issue.


If these suggestions don't resolve the issue, you can provide snippets of your ASPX page and code-behind where the RadButtons are defined and handled. This will help in giving a more specific solution. You can also open a support ticket and share a simple working project which demonstrate the problem.
