Hello,

I apologize for the inconvenience.

Please try to use “DoResize” method in “OnShowDropDown” client side event.

Here’s the example snippet code how to use “DoResize” method:

<ISWebCombo:WebCombo ID="WebCombo1" runat="server">    <LayoutSettings>
        <ClientSideEvents OnShowDropDown="WebCombo1_OnShowDropDown" />
    </LayoutSettings>
</ISWebCombo:WebCombo>

function WebCombo1_OnShowDropDown(controlId, left, top, width, height)
{
    var WebCombo1 = ISGetObject(controlId);
    WebCombo1.DoResize();
}

Hope this helps.

Regards,
Hans K.
