        TxtName.Text = r.Cells[0].Text;
        TextBox2.Text = r.Cells[1].Text;
        TextBox3.Text = r.Cells[2].Text;
        TextBox4.Text = r.Cells[3].Text;
    }

Answer 1

You must use EnableViewState="true" and bind just one time with ! IsPostBack ! IsPostBack in order to not erase your event foreach post.

because when your re build your grid you erase all events

In your page load :

if(! IsPostback)
{
   //Bind your Gridview
}

Persist your datas with EnableViewState="true"

 <asp:gridview id="YourGridView"  EnableViewState="true" ...../>

Answer 2

我们需要启用选择按钮，然后仅触发GridView1_SelectedIndexChanged，即AutoGenerateSelectButton =“ true”
