Gridview Sort 'onsorting' question...

[VisualGuy]

I'm trying to capture a sorting event and have it so that before it actually does the sort on the gridview, a textbox value on the page say's "one moment..."

The "one moment..." is listed within javascript on the actual page. However, I don't know how to talk to the page, prior to calling RunQuery, which handles the sort.

Any ideas...

Protected Sub GridView2_Sorting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewSortEventArgs) Handles GridView2.Sorting

If Not Me.Page.IsPostBack Then
Me.GridView2.Attributes.Add("OnSorting", "Sort_msg(this);")
End If

'Run Public Sub
RunQuery(SearchVal)
End Sub

when you mean talk to the page, do you mean html? if so you cannot. this is the nature of web development.
1. send request from client to server
2. server process request
3. send response from server back to client

each request/response is an atomic unit unaware of any other requests. to get an "interactive" fell to the webpage with status updates you need to use ajax. ajax still follows the pattern above, but it doesn't require the entire page to refresh to update information.

there are many javascript libraries out there that do the heavy lifting of ajax for you. jquery is the most popular, along with prototype, dojo, and ms ajax.
