call a function

[dorandoran]

How do I call following function from a Text Link?
Like, I want to call the export function when user click on this link.
Click here to Export to Excel

I tried this but it's not working.
<a href="Export2Excel()" id="link">Export to Excel</a><br />

    protected void Export2Excel()
    {
        Response.Clear();
        Response.Buffer = true;
 
        Response.AddHeader("content-disposition", "attachment;filename=EmployeeList.xls");
        Response.Charset = "";
        Response.ContentType = "application/vnd.ms-excel";
        StringWriter sw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(sw);
 
        GridView2.AllowPaging = false;
        GridView2.DataBind();
 
        for (int i = 0; i < GridView2.Rows.Count; i++)
        {
            GridViewRow gvRow = GridView2.Rows[i];
        }
        GridView2.RenderControl(hw);
        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();
    }

i think you should use link botton of asp instead of <a/> and in its onclick event call your function.
or
use onclick event in your <a/> tag with runat server = true i think u can do this from here but i m not sure but in case of linkbutton i m sure you can call a function

Instead of using an HTML hyperlink, use a LinkButton and configure it so that it calls that function during the OnClick event.

You could either add an event handler to the LinkButton in your C# code, or you could add set the OnClick property of the LinkButton in your ASP code to the function.

For Example (ASP method):

<asp:LinkButton id="exportToExcel" runat="server" OnClick="Export2Excel()" Text="Export to Excel></asp:LinkButton>

C# method:

exportToExcel.Click += new EventHandler(Export2Excel);

For this to work you have to change your Export2Excel method definition to:

protected void Export2Excel(object sender, EventArgs e)
