Find the control using FindControl method and put it in a variable

Like
TextBox tb = (TextBox)datalist1.FindControl("text1");
int x;
x = convert.ToInt32(tb.Text);

{


string b;
Label z = (Label)(DataList1.FindControl("Lbl1"));
Response.Redirect(z.ToString());

You can find textbox inside datalist in a imagebutton click event. IF ur image button is inside the datalist then use your code in datalist itemcommand event.
