RadGrid inside a RadCombobox using GridTemplateColumn

[Patrick]

I have an ASP:Gridview with RadComboBoxes set up inside of that.  These RadComboBoxes have their items dynamically created, so each RadComboBox has their items different from another RadComboBox.  This was all well and great until I was instructed to insert 10 columns.  Since the RadComboBox's header refuses to scroll along with the items, I feel like I'm forced to use a RadGrid inside of the RadComboBox.  I was thinking I could use a GridTemplateColumn to accomplish the goal.  Unfortunately, all I'm getting are two thick lines with no data inside of them.  Can you take a look at the following code and possibly help me out, please?  Maybe I totally screwed things up...

ASPX:

<telerik:RadComboBox ID="cboDupChoices" runat="server" DropDownWidth="600px"

  EnableLoadOnDemand="false" style="display:none">

    <ItemTemplate>

        <telerik:RadGrid ID="x" runat="server" Height="300px">

            <MasterTableView AutoGenerateColumns="false">

                <Columns>

                    <telerik:GridTemplateColumn HeaderText="Test">

                        <HeaderStyle Width="75px" />

                        <ItemTemplate>

                            <%# DataBinder.Eval(Container, "Attributes[""ID1""]")%>

                        </ItemTemplate>

                    </telerik:GridTemplateColumn>
... REPEAT 9 MORE TIMES ...

                </Columns>

            </MasterTableView>

            <ClientSettings>

                <Scrolling AllowScroll="true" UseStaticHeaders="true" ScrollHeight="300px" />

            </ClientSettings>

        </telerik:RadGrid>

    </ItemTemplate>

</telerik:RadComboBox>

VB:

cboTest.Style.Value = "display:block"

cboTest.Items.Clear()

 

Dim lnJ As Integer = 0

For Each dupFile As FILE In dupFiles

    ' Add item template here.

    Dim test As RadComboBoxItem = New RadComboBoxItem()

    test.Attributes("ID1") = dupFile.FIELD1

    test.Attributes("Status") = dupFile.FIELD2

    test.Attributes("Department") = dupFile.FIELD3

    test.Attributes("Description") = dupFile.FIELD4
... REPEAT 6 MORE TIMES ...

 

    test.Value = dupFile.FILEID

    test.Text = dupFile.FILEID

    cboTest.Items.Add(test)

    cboTest.Items(lnJ).DataBind()

    lnJ = lnJ + 1

Thanks for any help you may have,

Nesting a grid in combo is quite complicated.
Have you tried to set the DropDownWidth property of the combo?
If you set the width to some appropriate value - all 10 columns will be visible.

Yeah I agree.  I did find a way to get a successful grid inside of a combobox, but because there were fields that were numerous in number, all of the headers spilled outside of the combobox, or I could scroll through the combobox, but the header row was not scrolling along with the rest of the grid.  As I was finding no solutions to this issue besides changing controls, I gave up on that idea and I am now trying a Hierarchical RadGrid solution.  I think I'm having much better luck there.

Thank you for your assistance.
