Hi a.bek,

Please find below a sample code snippet that shows the needed approach.

<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>

    <script language="javascript" type="text/javascript">
    function OnClientDropDownOpening(sender, eventArgs)
    {
        if(sender.get_items().get_count() != 0)
        {
            sender._dropDownWidth = "400";
        }
    }
    </script>

    <telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientDropDownOpening="OnClientDropDownOpening">
        <Items>
            <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1" Value="RadComboBoxItem1" />
            <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem2" Value="RadComboBoxItem2" />
            <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem3" Value="RadComboBoxItem3" />
        </Items>
        <CollapseAnimation Duration="200" Type="OutQuint" />
    </telerik:RadComboBox>
</form>

Hi Paul

thnks for the code i need something more

suppose i have a grid inside the combo and i need to set the dropdownwidth so no horizontal scrollbars to be visible

please provide some sample code

Hi a.bek,

If your grid has fixed width you can achieve your goal using the provide code snippet.

<script language="javascript" type="text/javascript">
    function OnClientDropDownOpening(sender, eventArgs)
    {
        if(sender.get_items().get_count() != 0)
        {
            sender._dropDownWidth = "400" + "16";
        }
    }
    </script>

Hi Paul

the problem is that the grid does not have fixed width it uses the default one and i do not know how is calculated/obtained on the client side

Hi a.bek,

Unfortunately without setting explicitly fixed width for the grid which resides in the combobox dropdown, you are not able to determine what size to set for the combobox popup container.

You should either use the approach described below in this thread or expand the RadComboBox dropdown width to 100% to ensure that the embedded grid will fit in it. I hope that one of these options is feasible for your particular case.

I am using version 2.1.1 of the RadCombo (not ajax).  is there a way of changing the width in 1.1?

Thanks,
