Solution 1

Add an event to the button Button1_Click then in that click event (bubble event) you can find the control

C#

protected void Button1_Click(object sender, EventArgs e)
{
GridViewRow row=((Button)sender).Parent.Parent as GridViewRow;
TextBox t=(TextBox)row.FindControl("textbox ");
//t.Text - here is your value
}

Is this button in the same row/ outside the grid?

just remove the space, (TextBox)row.FindControl("textbox");
