RadPanelBar within Formview

[Jun]

I am looking for an example where the the radpanelbar items contain bindable controls from the datasource specified within a formview. I made the following layout but binding would not work. The bindable  column1 (in bold) below is not populated. Any better approach in handling a bindable data entry form within a radpanelitem? Please help.

<formview id="test" runat="server" datasource="onesource">

<EditItemTemplate>

<telerik:radpanelbar>

<items>

<telerik:RadPanelItem Text="1st bar" Expanded="true" >

<Items>

<telerik:RadPanelItem Value="clInfo" >

<ItemTemplate>

<asp:TextBox id="txt1st" runat="server" Text= '<%# Bind("Column1") %>'

<ItemTemplate>

</telerik:RadPanelItem>

</items>

</telerik:RadPanelItem>  </items>

</telerik:radpanelbar>

</EditItemTemplate>

<InsertItemTemplate>

....

....

</InsertItemTemplate>

</formview>

Hello,

You can bind the textbox using the Eval method as shown below:
aspx:

 <telerik:RadPanelItem Value="clInfo" runat="server">
        <ItemTemplate>
              <asp:TextBox ID="txt1st" runat="server" Text='<%#DataBinder.Eval(FormView1.DataItem,"Column1")%>'></asp:TextBox>
        </ItemTemplate>
 </telerik:RadPanelItem>

Thanks
Princy.

Princy,

It worked. Thanks a lot. Do you have an explanation on why Bind would not work? If you don't have  a time to answer this, that is fine. I really appreciate your prompt response.

Hi Jun,

Go through the following article which gives an overview of Data-Binding Expressions.
Data-Binding Expressions Overview

Here is an asp.net forum which explains the difference between DataBinder.Eval and Eval.
DataBinder.Eval vs Eval

Thanks

I managed to databind using this technique, however, when listening to the ItemUpdating-event of the formview, e.OldValues and e.NewValues are empty. What should I do?
My FormView is bound to an ObjectDataSource, so they should be populated.

Using Eval does not provide two-way binding so your solution is not correct as a replacement for Bind("someProperty"). How do we get back two-way binding in a PanelBarItem inside an EditItemTemplate?

Hello,

In this case the only workaround would be to implement two-way binding functionality manually. When user updates the data you can access the RadPanelBar control withing the form view and retrieve its text box values  and update the data source manually.
