I can't get a grid checkbox column to display at all in any browser

<telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">
                                    <ItemTemplate>
                                        <asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="ToggleRowSelection"
                                            AutoPostBack="True" />
                                    </ItemTemplate>
                                    <HeaderTemplate>
                                        <asp:CheckBox ID="headerChkbox" runat="server" OnCheckedChanged="ToggleSelectedState"
                                            AutoPostBack="True" />
                                    </HeaderTemplate>
</telerik:GridTemplateColumn>

 

 

<input id="ctl00_ContentPlaceHolder2_grdAccounts_ctl00_ctl04_CheckBox1" type="checkbox" name="ctl00$ContentPlaceHolder2$grdAccounts$ctl00$ctl04$CheckBox1" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder2$grdAccounts$ctl00$ctl04$CheckBox1\',\'\')', 0)">

 

I've tried the template and the gridcheckboxcolumn.

 

Nothing displays no matter what approach I take.  I am using a NeedDataSource method.

 

I've searched the forums and tried pretty much everything I've found.

 

Please help.

Thanks,
Jason

Hi Jason,

There are a couple of common problems leading to the described behavior. 

Please try the suggestions in the following knowledge base article and let me know if this helps:

• CheckBoxes are not visible in RadGrid
  

If this is not the case, please share the complete markup of the page containing the RadGrid so we can take a look and see if we can define the cause of the problem.

It would also help if you capture the current behavior with the Fiddler Jam tool and share the log with us. You can create a capture by using the link below and by following the instructions on the fly:

• Predefined Link to start a capture

You can find more about Fiddler Jam and how to use it here - Capture network logs & log issues with Fiddler Jam in ASP.NET Web Forms

Looking forward to your feedback.

Kind regards,
Doncho
