    I have a RadGrid and a button that loads the grid based on a search string, and use the loading panel when the user hits the search button. I have a javascript function validate() on the button to validate if use enters search criteria, if I remove this javascript function from the button, the loading panel works fine. But if I add this function nothing happens when clicking search button even though the function return true.

    the code is as below:
    function validate() {
            if (document.getElementById("<%=txtQueryText.ClientID%>").value == "") {
                alert("Please enter search keyword!");
                document.getElementById("<%=txtQueryText.ClientID%>").focus();
                return false;
            }
            else return true;
        }
      
      
    <AjaxSettings>
                    <telerik:AjaxSetting AjaxControlID="BtnSearch">
                        <UpdatedControls>
                            <telerik:AjaxUpdatedControl ControlID="RadGridResults" LoadingPanelID="RadAjaxLoadingPanel1"/>
                        </UpdatedControls>
                    </telerik:AjaxSetting>
                </AjaxSettings>
    <asp:Button ID="btnSearch" runat="server" Text="<%$ Resources:GUI,Button.Search %>" OnClick="btnSearch_Click"  OnClientClick="return validate()" />


    Does it support client script button or what could be wrong.

    Please help. Thanks.

    Hello Connie,

    I would suggest you to refer to the help topic below. It elaborates on executing custom javascript after ajax request:
