You'll have to use javascript code for setting focus. This can be done in the
codebehind file as follows:
(1) Write a method, say, SetFocus(Control x), which will register a
javascript code block.
(2) Call the SetFocus method with a control parameter from another method,
or event handler, say, Page_Load or Button1_click
(3) For detailed articles, follow this link
http://www.aspnetworld.com/articles/2004030301.aspx

The sample code is as follows:
private void SetFocus(Control x)
{
string clientId = x.ClientID;
StringBuilder strScript = new StringBuilder("<script
language='javascript'>\n");
strScript.Append("document.getElementById('" + clientId +
"').focus();\n");
strScript.Append("</script>\n");
Page.RegisterStartupScript("Focus",strScript.ToStr ing());
}

private void Button1_Click(object sender, System.EventArgs e)
{
SetFocus(TextBox2);
}

Hope this helps.
