Question

My newly created button in my gridviewrow is not firing its EventHandler or the RowCmmand Event and then when the page Reload after pressing the Button newly added row is missing probably because I can’t call my BindData method. I have removed the Click eventHandler from the Button and just used the OnRowCommand Event and I still am getting nothing

protected void CustomGridView_DataBound(object sender, EventArgs e)
{
    int count = ((GridView)sender).Rows.Count;
    GridViewRow row = new GridViewRow(-1, -1, DataControlRowType.DataRow, DataControlRowState.Insert);

    TableCell cell = new TableCell();
    Button button = new Button();
    button.Text = "Insert";
    button.ID = "Insert";
    button.CommandName = "Insert";
    button.Click += new EventHandler(insertButton_Click);

    cell.Controls.Add(button);
    row.Cells.Add(cell);

    for (int i = 0; i < ((GridView)sender).Columns.Count; i++)
    {
        cell = new TableCell();
        cell.Controls.Add(new TextBox { ID = "Text" + i });
        row.Cells.Add(cell);
    }

    Table table = ((GridView)sender).Rows[0].Parent as Table;
    table.Rows.AddAt(count + 1, row);
}

protected void insertButton_Click(object sender, EventArgs e)
{
    lblInsert.Text = "Hello World";
}

protected void CustomGridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Insert")
    {
        lblInsert.Text = "Hello World";
    }
}

Remove the button.Click += new EventHandler(insertButton_Click); statement from your code. The RowCommand event of GridView controll will be fired when button is pressed. For more info – How to: Respond to Button Events in a GridView Control.
