获取在GridView中正在更新的当前行的值

Question

I have a GridView GridView1 and I want to

 protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    // Get value from row of GridView and update in query below... 
    SqlDataSource1.UpdateCommand = "UPDATE tblDonors SET DName = 'Dummy' WHERE DName = 'Test'";
}

How to get values of current row so that I can update that row in the Database.

I have tried this but does not work

GridView1.Rows[e.RowIndex].Cells[0].Controls[0].ToString();

Answer 1

You need to use GridView1.EditIndex instead of e.RowIndex.

TextBox Tb = (TextBox) GridView1.Rows[GridView1.EditIndex].FindControl("TextBox1");
if(tb!=null){
 string s = tb.Text;
}

Or Try this:

  TextBox Tb = (TextBox) GridView1.Rows[GridView1.EditIndex].Cells[0].Controls[0];
    if(tb!=null){
     string s = tb.Text;
    }

Also take a look at e.NewValues
