Change the order of client script / server script

rupen · April 16th, 2009, 08:23 AM

Hi All,

I have used OnClientClick method of server button control, but the script executes before the server-side code written in the click event of server button control, which i need to swap, i.e. server-side code should be executed first and then the client script.

Thanks in advance.

the OnClient executes first because that event happens first... you could registerclientscriptblock and have that run after the server side code?

something like

Code:

Protected Sub Button1_Click (ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        'Your server side code here

        Dim strScript As New StringBuilder
        strScript.Append("<script language='javascript' type='text/javascript'>")
        strScript.Append("alert('This alert is happening after the post back!');")
        strScript.Append("</" & "script>")
        Page.ClientScript.RegisterClientScriptBlock(Page.GetType, "ClientScript", strScript.ToString, False)


End Sub

Sorry to say this, but what's the point?? the Whole point of executing client script before server script is to avoid the round trip between client and server... if you will be doing the trip, why not execute just all the code in the server???

I don't really see the point but i was just giving an option as to what they could do... Perhaps there is a valid reason (but i doubt it)
