If it's asp.net (page.aspx would indicate this) you just need an event, say a button click to generate the postback, from which you can call the method you want.
Or, script callbacks, http://www.developer.com/net/asp/article.php/3485991[^]

could you explain to me how to this please?
I mean, what I'm trying to do is to use a method \ function from VB\C#.NET compiled class in the App_Code folder from a simple html page at the OnClick etc. event that has been raised via a HTML and other pure client controls\events.

Hello all,
I am quite in a dilemma at the moment since i cannot find some independent reading which thoroughly describes the characteristics of j2ee vs .net.
I am experienced with .net but would like to know what the j2ee platform offers since several components used are totally free.
can anybody give me his/her views on the subject.
Thank you very much,
Chris

I'm working on an application which has a viewstate of approximately 250kb in a Notepad file. When doing a postback (e.g. on changing a dropdownlist's value) it takes a whopping 9 seconds to reload the page. This isn't really workable, problem is that I can't rebuild the application (as much as I'd like to) and I cannot disable the viewstate. Is there any way to speed this entire process off, or anything else that might be causing this besides the viewstate?

Rather than having the drop down list AutoPostBack, have you thought of using AJAX or JavaScript to handle the onchange event? Would be a lot quicker and provied a better user experience all round.

I know sorting can be done ascending/descending on a gridview.
Can it be done on each page of the grid when paging also is enabled?
Thanks
|
|
|
|
|
when you want to change your sort direction, aren't you have to bind the data again? that process will bring you back to page index 0, isn't it ?
well if you want to go to certain page, just assign that certain page index at gridview.currentpageindex ...
hope it helps..

I have a drop down list with gridview. When the page loads the option in the drop down is 'select an item'. However the gridview does not load all records when the page is first loaded and the user has not made a selection yet in the drop down. Here is my code:
<asp:dropdownlist id="DropDownList1" runat="server" autopostback="True" onselectedindexchanged="DropDownList1_SelectedIndexChanged">
<asp:listitem>Select an item
<asp:listitem>A
<asp:listitem>B
Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged
If DropDownList1.SelectedIndex.Equals(0) Then
tabledata.SelectCommand = ("SELECT * FROM [table]")
End If
End Sub
|
|

|

Hi,
You will need to handle the initial population of the DropDownList in Page_Load, or another page event, as the SelectedIndexChanged event of the list will not get fired on the inital GET of the page.
Hope this helps...

Use Request.QueryString["action"] to look for the value in the query string. The value returned is as string, which is null if the value was not present in the query string.
