Find RadComboBox in panelbar

[Luis]

Greetings

i have a RadPaneBar with a RadComboBox inside
and want to fill the combobox at runtime
for example:
     dim cmb as RadComboBox = ctype(RadPanelBar.parent.findcontrol("Comboname"),RadComboBox)
     dim a as integer
     for a = 1 to 30
        cmb.items.add(new RadComboBoxItem(a,a))
    next

and gave me this error

"Object reference not set to an instance of an object"

please help
thanks
Luis

Hi Luis,

You could get the reference to corresponding PanelBarItem and then use the FindControl() method to access the RadComboBox as shown below:

ASPX:

<telerik:RadPanelBar ID="RadPanelBar1" runat="server">
    <Items>
        <telerik:RadPanelItem Text="Item1">
            <ItemTemplate>
                <telerik:RadComboBox runat="server" ID="Combo1">
                </telerik:RadComboBox>
            </ItemTemplate>
        </telerik:RadPanelItem>
         . . .
    </Items>
</telerik:RadPanelBar>

CS:

protected void Button1_Click(object sender, EventArgs e)
{
    RadPanelItem panelItem = (RadPanelItem)RadPanelBar1.FindItemByText("Item1");
    RadComboBox combo = (RadComboBox)panelItem.FindControl("Combo1");
}
