Hi All,

I use the Infragestic WebDatePicker in GridView with UpdatePanel. Our Infragistics version is (Infragistics35.Web.v10.3, Version=10.3.20103.2120).

When Page Load or postback, infragistics WebDatePicker is not display popup calendar. But when click the grid event (AddNew,Update,Delete) calendar is display.

I have no idea, which place need to configure or fix ?

Below is my script sample -

<form id="frmBL" method="post" runat="server">
