Hi Christian,
Do you know any link?
Is it possible to implement this ajax concept in middle of the application development?

The ASP.NET AJAX library is easily found and downloaded if you look here[^].
Yes, you can add it any time you like.

how to determine if a datagrid has any data using a custom validator?
|

Well, why would you use a validator, when you'll know before you render the page that there's no data. What are you trying to do ? A validator runs on input.

can you be a bit elaborate your problem.
OK. I am giving a solution based on my previous problem if it fits ok.
function validateGridViewData()
{
rowCount = document.getElementById("gvProducts").rows.length;
if (rowCount >1)
return true;
return false;
}
And pass this function to the CustomValidator. Let me know does this solve your problem.

Tell em one thing, am i doing a right way
I have putted one script manager
and putted the gridview into the update panel and in page load i have putted
this.ScriptManager1.RegisterAsyncPostBackControl(this.Button1);
code....

Since I have some events related to GridView like on the click of that button I am going to fill the Grid i.e. the events are related to the GridView on the button click
so i have to give this syntax....
I had read this somewhere
|
|
|
|
|
OK
I can prefer to u, when u have fill gridview with data ,please write a method for that and call with in the pre_render event.
And remove that button set to scriptmanager as Async mode button .
after that see.
thanks

yes i had a separate method say "FillGrid()" which I call at the button_click event...
but on prerender it will fill grid before rendering where does AJAX work?
I do not want to refresh teh page when i click the button and it fills the grid

I have written the following code in aspx page
<asp:scriptmanager id="ScriptManager1" runat="server">
<asp:updatepanel id="UpdatePanel1" runat="server" updatemode="Conditional">
<triggers> <asp:postbacktrigger controlid="Button1">
<%--<asp:asyncpostbacktrigger controlid="Button2" eventname="Click"> --%>
<contenttemplate>
<asp:gridview id="GridView1" runat="server" autogeneratecolumns="False" datakeynames="ID" datasourceid="SqlDataSource1">
<columns>--------------
<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ------">
<asp:button id="Button1" runat="server" text="Button" onclick="Button1_Click">
and this is teh code on button click is used to perform some operations say fill grid
Now waht is the error in my code?
I m not getting what i m doing wrong?

Take both control,Gridview and Button,in update panel,set Updatemode as conditional.
Do not need to register button so remove this line ...............RegisterAsyncPostBackControl(this.Button1);
OR.
take gridview in update panel and button is out of update panel,set Updatemode as conditional.
set trigger of button click event in update panel.
