Hello Fabio,

Inorder to populate a combobox based on the item selected in another combobox, both comboboxes being placed in the DetailTable of a grid, when the detail table is in InsertMode only, you can try the following code:
c#:

protected void rdgWorkFlow_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted && e.Item.OwnerTableView.Name == "Detail")
        {
            GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;
            RadComboBox combo = (RadComboBox)insertItem.FindControl("rdbnil_c_divisao");
            combo.AutoPostBack = true;
            combo.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(combo_SelectedIndexChanged);
        }
    }

void  combo_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
{
    RadComboBox combo1 = (RadComboBox)o;
    RadComboBox combo2 = (RadComboBox)combo1.NamingContainer.FindControl("rdbnil_tar_n_codigo");
    if (combo1.SelectedItem.Text == "Text1")
    {
        combo2.DataSourceID = "SqlDataSource2";
        combo2.DataTextField = "Column2";
    }
}

Thanks
