Folks,

I am using RadControls for ASP.NET AJAX Q2 2009 SP1 with Visual Studio 2008 SP1.

I have a Heirarchical Grid (

MasterTableView

and DetailTables both uses FormTemplate). In DetailTables, I have a RadCombo Box. Is it possible:

1) In RadGrid1_UpdateCommand/ RadGrid1_InsertCommand Events, capture the Template Values of City and ContactTitle into string Variables? Neither City nor ContactTitle are DataTextField or DataValueField of ComboBox?

2) After the RadComboBox1_SelectedIndexChanged Event of ComboBox (autopost is set to true here), is it possible to update a label (ComboBoxContactTitle) in DetailTable Form Template?

Below is my code. Any help will be appreciated.

Thanks

Thanks Helen,

But one small change I had to make. In RadComboBox1_SelectedIndexChanged event, the label labelToUpdate.Text updated value

should not be combo.SelectedItem.Text but comboItem.Attributes["ContactTitle"]; That was my desire.

Any way is working now. Changes are in this color.

Sincerely

protected void RadComboBox1_SelectedIndexChanged(object o, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

RadComboBox combo = (RadComboBox)o;

RadComboBoxItem comboItem = combo.SelectedItem;

string contactTitle = comboItem.Attributes["ContactTitle"];

Label labelToUpdate = (Label)combo.NamingContainer.FindControl("ComboBoxContactTitle");

labelToUpdate.Text = contactTitle.ToString();

// labelToUpdate.Text = combo.SelectedItem.Text;

}

<telerik:RadComboBox runat="server" ID="RadComboBox1" DataTextField="ContactName"
