(3/3) ListView events, ItemEditing, ItemCanceling, ItemUpdating

Edit Record

Same for this Edit Record, Save Record and Cancel button click events.

Wire the events in the code-behind first.

LstItems.ItemEditing += new EventHandler<ListViewItemEventArgs>(LstItems_ItemEditing);
LstItems.ItemUpdating += new EventHandler<ListViewItemEventArgs>(LstItems_ItemUpdating);
LstItems.ItemCanceling += new EventHandler<ListViewItemEventArgs>(LstItems_ItemCanceling);

Button "Edit" click.

protected void LstItems_ItemEditing(object sender, ListViewItemEventArgs e)
{
    var item = LstItems.Items[e.NewEditIndex];

    // Save the currently selected item to OldDnsRecord

    // ReBind the ListView
}

Button "Save" click.

protected void LstItems_ItemUpdating(object sender, ListViewItemEventArgs e)
{
    if (!Page.IsValid)
    return;

    var txtNewHost = e.Item.FindControl<TextBox>("TxtNewHost");
    var txtNewPointsTo = e.Item.FindControl<TextBox>("TxtNewPointsTo");
    var ddlNewTtl = e.Item.FindControl<DropDownList>("DdlNewTTL");

    var host = txtNewHost.Text;
    var pointsTo = txtNewPointsTo.Text;
    var ttl = ddlNewTtl.SelectedValue;

    var result = UpdateExistingRecord();
    if (result == Status.Ok)
    {
        LstItems.EditIndex = -1;

        // Rebind the ListView
    }
    else
    {
        // Do error handling
    }
}

Button "Cancel" click.

protected void LstItems_ItemCanceling(object sender, ListViewItemEventArgs e)
{
        LstItems.EditIndex = -1;

        // Rebind the ListView
}
