Adding additional paging size limits

[Samir Vaidya]

I have turned on paging in my RadGrid control and the default limits for number of items per page are 10, 25 and 50.  However, I would also like to add additional limits for items per page for 75 and 100 in the dropdown list.

Is there a way to accomplish this in the RadGrid control?  If so, what are the settings that I need to modify?

Thanks.

hi,

protected void rad_ItemCreated(object sender, GridItemEventArgs e)
    {
    if (e.Item is  GridPagerItem)
        {
            GridPagerItem pager = (GridPagerItem)e.Item;
            RadComboBox PageSizeComboBox = (RadComboBox)pager.FindControl("PageSizeComboBox");
// add item by this way.
//            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
   }

Thanks,

Hello Samir,

Try the following code snippet in ItemCreated event to change the default limits for number of items in a page. Hope this helps.

C#:

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

       if (e.Item is GridPagerItem)           

        {

            GridPagerItem pagerItem = (GridPagerItem)e.Item;

            RadComboBox PageSizeCombo = (RadComboBox)pagerItem.FindControl("PageSizeComboBox");                 

            RadComboBoxItem item = new RadComboBoxItem();

            item = new RadComboBoxItem("75");

            item.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);

            PageSizeCombo.Items.Add(item);

        }

}


Thanks,
Princy.

The code that Princy provided works, however, when I Page through the RadGrid, the selection in the ComboBox is not retained.  In addition, if I add 2 values to the Paging Combobox such as 75 and 100, I get a duplicate of the 75 value upon paging through the Grid as well.

Please advise.

Hi Samir,

I followed your scenario and prepared a sample project which handles the desired functionality. You can find the example attached to this message. Please check it out and let me know if it works for you.
