I have a bound FormView that contained a series of controls including a bound RadTextBox.  For usability I placed a RadPanelBar inside the FormView and within the ItemTemplate moved the textBox.  The binding no longer is respected.  Should the binding have been preserved or what steps must be done to re-establish the binding?
Regards.

I don't think that will work since the RadTextBox is now inside of  a different container, RadPanelBar, which is not bound to the data the FormView is. So I don't think it's possible to do that.

Hi John,

Indeed you cannot use declarative databinding in the scenario that you describe.

However you can handle the FormView.DataBound event, find the RadPanelBar within the ItemTemplate, and use the FindItemByValue PanelBar method to find the exact item. Then obtain the RadTextBox control instance and set the text explicitly:
protected void FormView1_DataBound(object sender, EventArgs e)
{
    if (FormView1.CurrentMode == FormViewMode.ReadOnly)
    {
        DataRowView itemData = (DataRowView)FormView1.DataItem;

        RadPanelBar RadPanelBar1 =
                 (RadPanelBar)FormView1.FindControl(
"RadPanelBar1");

        RadPanelItem panelItem1 =
                  RadPanelBar1.FindItemByValue(
"RadTextBoxHolder");

        RadTextBox RadTextBoxProductName =
           (RadTextBox)panelItem1.FindControl("RadTextBoxProductName");

        RadTextBoxProductName.Text = itemData["ProductName"].ToString();
 
       ...
       ...
    }
}

Please find more details at the sample page attached.

All the best,
