I have written the below code for updating gridview, It's not working.

protected void Update_row(object sender, GridViewUpdateEventArgs e)
        {
            try
            {
  //TextBox ID = (TextBox)GridView1.Rows[e.RowIndex].Cells[0].FindControl("txtID");
  TextBox Title = (TextBox)GridView1.Rows[e.RowIndex].Cells[1].FindControl("TextBox1");
  TextBox Name = (TextBox)GridView1.Rows[e.RowIndex].Cells[2].FindControl("TextBox2");


                SPSecurity.RunWithElevatedPrivileges(delegate ()
                {
                    UpdateRow(ID.Text, Title.Text, Name.Text);
                    GridView1.EditIndex = -1;
                    Bind_Data();
                });
            }
            catch (Exception ex)
            {
                Label1.Text = ex.ToString();
            }

        }

After debugging I found that the ID, Title and Name values are null.

Updated

I found that I did not write the gridview code perfectly, so I made some changes there.

Now I am getting the values in those controls but these values are the already existing value, updated entries are not coming there.

Label ID = (Label)GridView1.Rows[e.RowIndex].Cells[0].FindControl("lblId");
                TextBox Name = (TextBox)GridView1.Rows[e.RowIndex].Cells[1].FindControl("txtName");
                TextBox Title = (TextBox)GridView1.Rows[e.RowIndex].Cells[2].FindControl("txtTitle");

these are just getting the already existing values.

  • Why u commented that ID TextBox? – Jayakumar Kulkarni Mar 8 '16 at 5:39

TRY THIS

 GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];         
    TextBox ID = (TextBox)row.FindControl("txtID");
    TextBox Title = (TextBox)row.FindControl("TextBox1");
    TextBox Name = (TextBox)row.FindControl("TextBox2");
