RadDataPager needs OnPageSizeChanged Event handler

[Mich Meow]

For consideration in a future release the RadDataPager should allow registration to an OnPageSizeChanged event. I am handling the databinding and paging in code behind going through a WCF tier; however, I had to remove the change PageSize functionality from the end user because this event doesn't exist.

The Functionality should be like this to mirror the PageIndexChanged event:

ASPX:

                <telerik:RadDataPager ID="RadDataPager1" runat="server" OnPageIndexChanged="RadDataPager1_PageIndexChanged"
                    OnTotalRowCountRequest="RadDataPager1_TotalRowCountRequest"
    OnPageSizeChanged="RadDataPager1_PageSizeChanged" Skin="Windows7">
                   ...
                </telerik:RadDataPager>

Code Behind:

    protected void RadDataPager1_PageSizeChanged(object sender, RadDataPagerPageSizeChangeEventArgs e)
    {
        int NewPageSize = e.NewPageSize;
...
    }

Cheers,
Andrew.

Hello Andrew,

You can handle OnCommand event of RadDataPager and listen for  RadDataPager.PageSizeChangeCommandName. For example:

Pager.Command += (s, a) =>
{
  if (a.CommandName == RadDataPager.PageSizeChangeCommandName)
  {
    var oldValue = Pager.PageSize;
    var newValue = Convert.ToInt32(a.CommandArgument);
  }
};

Thanks very much Nikolay, That worked perfectly for me.

Cheers,

I found that If I wanted the pager's PageSize property to actually reflect the selected value during the subsequent page render (as opposed to at the end of the render), I had to set it myself, to wit:

if (e.CommandName == RadDataPager.PageSizeChangeCommandName)
{
    (sender as RadDataPager).PageSize = Convert.ToInt32(e.CommandArgument);
}
