    hello,
    I have a grid which has a number of columns,
    one of the columns is combobox,
    I am getting Data from DB from 2 Tables:

    1. a table that populates the combobox - display, code.
    2. a table that populates the grid - fields+display.

    my problem is that I Indeed get the comboboxes full, but the selected items are always blank .

    i tried to change it to label instead of combobox and then i got it right,
    but I want it to be combobox.

    P. S. I want the combobox to be always avalable to change, without editmode.

    Hello Yoni,

    I am not quite sure about your requirement and I suppose you want to get the ComboBox i normal mode. if thats is your case you can add the control in ItemTemplate , it will be available in normal mode.

    Here is a sample code:
    aspx:
    <telerik:GridTemplateColumn HeaderText="TextBoxcol" UniqueName="ComboBoxcol">
        <ItemTemplate>
            <telerik:RadComboBox ID="RadComboBox1" runat="server"  Width="200px" DataSourceID="SqlDataSource1" EmptyMessage="Select An Item" DataTextField="FirstName">
            </telerik:RadComboBox>
          </ItemTemplate>
    </telerik:GridTemplateColumn>

    Thanks,
    Shinu.

    Hi Yoni,

    In order to determine what is causing this problem in your scenario we would need some more information. Please share with us your declaration of the RadGrid along with the RadComboBox and the way you bind them to a data source.

    Thanks for the help
    it works!!
    my problem was, i did this code in the Combo_Init instead of putting it in the RadGrid1_ItemDataBound

     

    now i put it there (RadGrid1_ItemDataBound) and it works.

     

    TryCast(e.Item.FindControl("RadComboBox1"), RadComboBox).DataTextField = "ModelDesc"
      
    TryCast(e.Item.FindControl("RadComboBox1"), RadComboBox).DataValueField = "ModelId"
      
    TryCast(e.Item.FindControl("RadComboBox1"), RadComboBox).DataBind()
      
    TryCast(e.Item.FindControl("RadComboBox1"), RadComboBox).SelectedValue = SelectedValueString
