Radwindow is not opening at button column click event in RadGrid

[Jessy Joseph]

I have a Radgrid with button column when I click the button the first time the Radwindow does not open, but it opens on the second click on the same button. I have tried every possible solution in RadAjax but still facing the same problem. I am using Masterpage in this project.

Following are my code in Javascript,Client side and Server side.

//Javascript Code

function ShowUPExc(partnerid) {

                window.radopen("Update.aspx?PartnerID=" + partnerid , "rwUpdateExc");
                return false;
                }

//Client Side Code

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="rgExc">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rgExc" />
                    <telerik:AjaxUpdatedControl ControlID="btnUpdate" />
                    <telerik:AjaxUpdatedControl ControlID="RadWindowManager1" />
                </UpdatedControls>

Hello Jessy,

To use the RadAjaxManager control in integration with a RadWindow as demonstrated in thisDemo you should use a separate RadWindow control and not to wrap it in a RadWindowManager.

Hope it will help,
Princy.
