Ok,
(1) Create an event on u'r user control
(2) Raise this event on when select value from list box
(3) Trace this event on your Aspx page where u have to use user control.

Note: If you have to use C#, Then use Delegates for the trap the event

or

If you use VB.Net then u can use withevent .

Hold the Hashtable in session and then get the hashtable in javascript on click of button, client side.
And set the data in chat window.

you can have a HTML button control...but what you actually need????.....
there DropDownList(and other controls) which has a click event and you can handle the postback also...but will it serve your need???

Export to Excel Problem [modified]

I used the below code to Export my gridview to excel. I have paging set to true. I am facing 2 problems. (1)Error: RegisterForEventValidation can only be called during Render(). This error got resolved when I turned the EventValidation to false. This could be a security risk. Can u help me with this? (2) After the 1st problem is resolved temporarily, the next problem is that the entire DataSet doesn't get exported. Only the current page gets exported. I need paging, so is there a way where I can get the entire DataSet which is bound to the gridview control exported to excel . Please help....Let me know if you need any of my code snippet. Thanks..

Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=Test.xls");
Response.Charset = "";

Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);

GridView1.RenderControl(htmlWrite);

Response.Write(stringWrite.ToString());
Response.End()

I have got the Idea from here[^] for my Qn. #1

Did u use VerifyRenderingInServerForm() ??

Re: Export to Excel Problem

1) I have already tried that one.

public override void VerifyRenderingInServerForm(Control control)
{
}

2) Tried like below also.

//Create a form to contain the grid

HtmlForm frm = new HtmlForm();
GridView1.Parent.Controls.Add(frm);
frm.Attributes["runat"] = "server";
frm.Controls.Add(GridView1);
frm.RenderControl(htmlWrite);
