Question

I have a GridView that was changed to a RadGrid, now before the GridView had the paging using a drop down above it with the following options to show items per page

 <asp:DropDownList ID="lstPage" runat="server" AutoPostBack="true" OnSelectedIndexChanged="lstPage_OnSelectedIndexChanged">
            <asp:ListItem Value="5">5</asp:ListItem>
            <asp:ListItem Value="15" Selected="True">15</asp:ListItem>
            <asp:ListItem Value="20">20</asp:ListItem>
            <asp:ListItem Value="50">50</asp:ListItem>
        </asp:DropDownList>
    </div>

But now with the RadGrid I am not sure how to do that? and I cant find the specific example on their site. Is there a way to tell the rad grid to use those custom values? 10,35,60,100> I am required to show the same options in tha paging.

Thank you

Method 1:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)   
{   
  if (e.Item is GridPagerItem)   
  {   
    RadComboBox PageSizeCombo = (RadComboBox)e.Item.FindControl("PageSizeComboBox");   

    PageSizeCombo.Items.Clear();   
    PageSizeCombo.Items.Add(new RadComboBoxItem("15"));   
    PageSizeCombo.FindItemByText("15").Attributes.Add("ownerTableViewId", RadGrid1.MasterTableView.ClientID);   
    PageSizeCombo.Items.Add(new RadComboBoxItem("50"));   
    PageSizeCombo.FindItemByText("50").Attributes.Add("ownerTableViewId", RadGrid1.MasterTableView.ClientID);   
    PageSizeCombo.Items.Add(new RadComboBoxItem("150"));   
    PageSizeCombo.FindItemByText("150").Attributes.Add("ownerTableViewId",   RadGrid1.MasterTableView.ClientID);   
    PageSizeCombo.Items.Add(new RadComboBoxItem("250"));   
    PageSizeCombo.FindItemByText("250").Attributes.Add("ownerTableViewId", RadGrid1.MasterTableView.ClientID);   
    PageSizeCombo.FindItemByText(e.Item.OwnerTableView.PageSize.ToString()).Selected = true; 
  }
}

Method 2:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
  if (e.Item is  GridPagerItem)
    {
        GridPagerItem pager = (GridPagerItem)e.Item;
        RadComboBox PageSizeComboBox = (RadComboBox)pager.FindControl("PageSizeComboBox");
        RadComboBoxItem ComboItem = new RadComboBoxItem("All");
        PageSizeComboBox.Items.Insert(0, ComboItem);
        PageSizeComboBox.AutoPostBack = true;
        PageSizeComboBox.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(PageSizeComboBox_SelectedIndexChanged);
    }
  }

  void PageSizeComboBox_SelectedIndexChanged(object sender,    RadComboBoxSelectedIndexChangedEventArgs e)
  {
    //Handle the event
  }
}
