Thanks for your prompt reply Peter,
Now I got that you want to do some resizing work on the GridView after page
index changes, then I think the first approach I mentioned earlier (about
emiting script in "PageIndexChanged" event should work.
As you said that the "alert" didn't popup, I think there might be something
else cause this. Is your page a standard ASP.NET page, or have you used any
AJAX feature such as updatepanel? There might be some problem with some
GridView events in updatepanel.
Here is my complete page code for the test(a standard simple aspx page):
======================
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AutoGenerateColumns="False" DataKeyNames="id"
DataSourceID="SqlDataSource1"
onpageindexchanged="GridView1_PageIndexChanged"
onprerender="GridView1_PreRender" PageSize="2">
<Columns>
<asp:BoundField DataField="id" HeaderText="id"
ReadOnly="True"
SortExpression="id" />
<asp:BoundField DataField="name" HeaderText="name"
SortExpression="name" />
<asp:BoundField DataField="age" HeaderText="age"
SortExpression="age" />
</Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:testdbConnectionString %>"
SelectCommand="SELECT [id], [name], [age] FROM [persons]">
</asp:SqlDataSource>
</form>
============================
========code behind=============
protected void GridView1_PageIndexChanged(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(this.GetType(),
"page_index_script", "alert('page index changed!');", true);
}
=================
Also, you can just define a javascript function statically in the aspx
template and reference it in the "RegisterStartupScript" function's
parameter. If necessary, I can send you the web project contains the page
for testing. Please feel free to let me know if there is anything else
different.

I have JavaScript resizing code, when the window is resized I use

>Hi Peter,

So far based on my understanding, here are some possible approaches we
can
>add client script behavior at Gridview's paging stage:
1. You can use Gridview's PageIndexChaged event and use
"ClientScript.RegisterStartupScript" to emit some clientscript to
client-side for execution(when the page's output is rendering in client
browser).
=======GridView page index changed===========
protected void GridView1_PageIndexChanged(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(this.GetType(),
"page_index_script", "alert('page index changed!');", true);
}
====================
2. If you need to do some pre processing(such as right after the user
change Gridview page), I think you may consider customize the Pager of
the
>gridview. for example, you can define the pager yourself (such as put two
"Move Next" and "Move Previous" buttons ) and you can add script
functions
>for the two button's click event(one is to do some tasks you want
client-side, another is postback to change page index).
For custom paging, here is an example:
