Solution 1

On row databound event create a textchanged event.

TextBox txt = e.Row.FindControl("TextBox1") as TextBox;
 txt.TextChanged += new EventHandler(TextBox1_TextChanged);

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
//your code
}

Object reference not set to an instance of an object.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
TextBox txt = e.Row.FindControl("TextBox1") as TextBox;
txt.TextChanged += new EventHandler(TextBox1_TextChanged);

Check whether you are giving correct idof textbox. I gave TextBox1 as example.
