Hi @Gani_tpt,

There is a problem with the following line of code. The way you wrote it is wrong.

window.location='window.close();'

The window.location object can be used to get the current page address (URL) and to redirect the browser to a new page.

Window close():closes a window.

The two should not be used together.

If you want to use window.location, you can use window.location.href to return the href (URL) of the current page.

        Dim Msg As String
        Msg = "Rec. updated successfully."
        System.Web.UI.ScriptManager.RegisterClientScriptBlock(Me.Page, Me.GetType(), "ClosePopup", "alert('" + Msg + "');window.location.href = 'https://localhost:44395/WebForm2';", True)

Or you can close the ASP.NET modal popup directly:

  Dim Msg As String
        Msg = "Rec. updated successfully."
        System.Web.UI.ScriptManager.RegisterClientScriptBlock(Me.Page, Me.GetType(), "ClosePopup", "alert('" + Msg + "');$('#YOURModalID').modal('hide');", True)
