     Hi,I have a problem with RadDataForm and HiddenField. I have a scenario like this:

 

 <telerik:RadDataForm runat="server" ID="radDataForm" DataSourceID="myDataSource">

   <InsertItemTemplate>

        <asp:HiddenField ID="hiddenField" runat="server" Value='<%# Bind("MyProperty") %>' />

         <telerik:RadComboBox ID="myCombo" runat="server" SelectedValue='<%# Bind("MyProperty2") %>' />

   </InsertItemTemplate>

</telerik:RadDataForm>

I Just semplify my code. The problem is that radComboBox (as other telerik controls) works fine and i bind my object passed in data source, while the property bounded throught asp:HiddenField doesn't work, even the value is not null.

Any suggestions?

 

Thanks

Hi Claudio,

Can  you elaborate a bit on the moment in which you are trying to access the Hidden field value? You can find an useful sample on how to access the controls inside the data item templates here:
https://docs.telerik.com/devtools/aspnet-ajax/controls/dataform/server-side-programming/access-controls-inside-templates#how-to-access-controls-inside-templates

You can also try binding the hidden field through the container dataitem like follows:
<asp:HiddenField ID="hiddenField" runat="server" Value='<%# DataBinder.Eval(Container.DataItem, "MyProperty") %>' />

Regards,
Vessy
