Customize Paging - Page Sizes

[SHP]

I have seen solutions for this issue in the RadGrid forum but they don't work for TreeList.  Basically I want to replace the page size option with my own set, but when I do that using the following code it breaks paging (changing the page size basically does nothing).  Evidently there is some event-handling that needs to be hooked up.  How do I get this to work?? Thanks in advance!

 Dim ddPageSizes As Telerik.Web.UI.RadComboBox = CType(e.Item.FindControl("PageSizeComboBox"), Telerik.Web.UI.RadComboBox)

                    ddPageSizes.Items.Clear()

                    ddPageSizes.Items.Add(New Telerik.Web.UI.RadComboBoxItem("10"))
                    ddPageSizes.Items(0).Attributes.Add("ownerTableViewId", Me.EditResults.ClientID)
                    ddPageSizes.Items.Add(New Telerik.Web.UI.RadComboBoxItem("250"))
                    ddPageSizes.Items(1).Attributes.Add("ownerTableViewId", Me.EditResults.ClientID)
                    ddPageSizes.Items.Add(New Telerik.Web.UI.RadComboBoxItem("500"))
                    ddPageSizes.Items(2).Attributes.Add("ownerTableViewId", Me.EditResults.ClientID)

                    ddPageSizes.FindItemByText(Me.EditResults.PageSize.ToString()).Selected = True

Hello Sean,

I have assembled a sample project demonstrating the desired functionality. The main steps for achieving your scenario are described below:

• Subscribe to RadTreeList ItemCreated event
• Find the pager RadComboBox and add all the items
• Select the current PageSize in the combo

protected void RadTreeList1_ItemCreated(object sender, Telerik.Web.UI.TreeListItemCreatedEventArgs e)
{
    TreeListPagerItem pagerItem = e.Item as TreeListPagerItem;

    if (pagerItem != null)
    {
        RadComboBox combo = e.Item.FindControl("PageSizeComboBox") as RadComboBox;
        combo.Items.Clear();
        IList<int> defaultPageSizes = new List<int>();
        defaultPageSizes.Add(10);
        defaultPageSizes.Add(250);
        defaultPageSizes.Add(500);
        foreach (int size in defaultPageSizes)
        {
            RadComboBoxItem item = new RadComboBoxItem(size.ToString(), size.ToString());
            combo.Items.Add(item);
        }
        RadComboBoxItem comboBoxItem = combo.Items.FindItemByValue(pagerItem.OwnerTreeList.PageSize.ToString());
        if (comboBoxItem != null)
        {
            comboBoxItem.Selected = true;
        }
    }
}

It works!  Thank you!!!!  I had actually tried that variation before but had mistakenly put the code into the ItemDataBound event handler instead of ItemCreated.  Thanks again!
