Unable to get the value in the TextBox in the GridView template column, which expert helps to see.

The second column of the GridView is the template column, there is a TextBox, and the first column is the bound column. I use the following code to iterate through the values ​​in the TextBox but the values ​​are always empty.
 int iNum = GridView1.Rows.Count;
        for (int i = 0; i <iNum; i ++)
        {
            GridViewRow selectedRow = GridView1.Rows [i];
            TableCell contactName = selectedRow.Cells [0];
             TableCell tempCell = selectedRow.Cells [1];
     
                TextBox textBox1 = (TextBox) tempCell.FindControl ("TextBox1");
                strNum = textBox1.Text;
                strTitle = contactName.Text;
                hash.Add (strTitle, strNum);
            }
        
        }

Is it possible to mix template columns and binding columns?

No problem.

Yeah, I'm also baffled.

Explain when it should have value.

Where is this code written? Is there any data binding at this time?

Written in the Click event of another Button on the page, tried it for a long time, and finally solved it, thank you:
The code is changed to the following:
String strTitle, strNum;
        Hashtable hash = new Hashtable (50);
         int iNum = GridView1.Rows.Count;
        for (int i = 0; i <iNum; i ++)
        {

            CheckBox check = (CheckBox) GridView1.Rows [i] .Cells [0] .Controls [1];

            if (check.Checked)
            {
     
            TextBox textQuantity = (TextBox) GridView1.Rows [i] .Cells [2] .Controls [1];
                strTitle = GridView1.Rows [i] .Cells [1] .Text;

                strNum = textQuantity.Text;
                 hash.Add (strTitle, strNum);
             }
        
        }
       Session ["basket"] = hash;

Why I used the above method, but still can't get the modified value in the bound TextBox?
