    I have a RadCombo in the template for a RadToolBarButton in the RadToolBarDropDown.

    I want to allow the user to make a selection from the Combo Box and then have him click the RadToolBarButton to perform the post back.

    As soon as a selection is made from the combo box the RadToolBarDropDown closes. 

    I want to be able to leave the RadToolBarDropDown open after a selection has been made in the combo box and hence avoid an extra click which is currently needed to reopen RadToolBarDropDown. 

    I have attached the image with this message.

    Any insight will be greatly appreciated.

    Hello Imran,

    You should use OnClientDropDownOpening and OnClientDropDownClosed events of the combobox to mark whether the dropdown button should be closed like this:

    <telerik:RadToolBar ID="RadToolBar1" runat="server" OnClientDropDownClosing="dropDownClosing">
            <telerik:RadToolBarDropDown Text="dropdown">
                    <telerik:RadToolBarButton Text="dropdown 1" />
                            <telerik:RadComboBox ID="RadComboBox1" runat="server"  OnClientDropDownOpening="dropDownOpening"
                                    <telerik:RadComboBoxItem Text="item1" />
                                    <telerik:RadComboBoxItem Text="item2" />
                                    <telerik:RadComboBoxItem Text="item3" />

    and the needed javascript:

    <script type="text/javascript">
        var shouldClose = true;
        function dropDownOpening(sender, args) {
            shouldClose = false;
        function dropDownClosed(sender, args) {
            shouldClose = true;
        function dropDownClosing(sender, args) {
            if (!shouldClose)
