Checkbox in InsertItemTemplate not storing value

[Johann]

HI There

I'm working with a Radgrid and I'm having an issue whereby a checkbox in a TemplateColumn's InsertItemTemplate section is not storing it's value in the DB.

The Textbox in another column is working fine, and I can go and edit the Row afterwards and select the checkbox if I wanted to, that works. But, on Insert, the checkbox's checked state is not stored in the DB.

 

Here are the 2 columns (first one works fine, the other doesn't):

<telerik:GridTemplateColumn Reorderable="true" UniqueName="TemplateColumn" FilterControlAltText="Filter TemplateColumn column" DataField="typeofhardware" SortExpression="typeofhardware">
             <HeaderTemplate>
                 <asp:LinkButton Text="Type of HW" ID="HWSortbutton" ToolTip="Click to Sort" CommandName="Sort" CommandArgument="typeofhardware" runat="server" />
             </HeaderTemplate>

             <ItemTemplate>
                 <asp:Label Text='<%# Bind("typeofhardware") %>' ID="lblTypeofHW" runat="server" />
             </ItemTemplate>
             <EditItemTemplate>
                 <table style="width: 100%">
                     <tr>
                         <td>
                             <asp:Label Text="Type of Hardware" runat="server" />

                         </td>
                         <td style="width: 25px;"></td>
                         <td>
                             <asp:TextBox runat="server" ID="txtTypeOfHardware" Width="100%" Text='<%# Bind("typeofhardware") %>' />
                         </td>
                     </tr>
                 </table>

             </EditItemTemplate>
             <InsertItemTemplate>
                 Type of Hardware:
                 <asp:TextBox runat="server" Text='<%# Bind("typeofhardware") %>' ID="txtTypeOfHardware" />
             </InsertItemTemplate>
         </telerik:GridTemplateColumn>


         <telerik:GridTemplateColumn Reorderable="true" DataType="System.Boolean" UniqueName="HidemeColumn" FilterCheckListEnableLoadOnDemand="false" DataField="hideme" SortExpression="hideme">
             <HeaderTemplate>
                 <asp:LinkButton Text="Hidden?" ID="HiddenSortbutton" ToolTip="Click to Sort" CommandName="Sort" CommandArgument="hideme" runat="server" />
             </HeaderTemplate>
             <ItemTemplate>
                 <asp:CheckBox Checked='<%# Bind("hideme") %>' Enabled="false" ID="chkHidden" runat="server" />
             </ItemTemplate>
             <EditItemTemplate>
                 Hidden?:
                 <asp:CheckBox ID="chkHidden" runat="server"  />
             </EditItemTemplate>
             <InsertItemTemplate>
                 Hidden?:
                 <asp:CheckBox   ID="chkHidden" runat="server" />
             </InsertItemTemplate>

         </telerik:GridTemplateColumn>

I've tried many things to solve this, firstly tried Binding the checked property of the checkbox in the InsertItemTemplate like this:

<asp:CheckBox Checked='<%# Bind("hideme") %>' ID="chkHidden" runat="server" />

That produces a cast error though.

Doing this doesn't cause any error:

 

<asp:CheckBox Checked='<%# DataBinder.Eval(Container.DataItem, "hideme") is DBNull ? false : Eval("hideme") %>' ID="chkHidden" runat="server" />

The problem is however that when I submit the Insert Form, the value of the checkbox is not stored in the DB. 

Any ideas?
