Hi,

In RadGrid, is it possible to set multi-column filtering, what I mean by multi-column filtering is for the same column can I set a filter expression using logical operators, ie., like FilterExpression = "ID equals OR greater Than 10".(ID being the column)

How can I set the filter expression at code-behind?

Could u plz reply me with the code snippet....

Item highlighting not working onmouseover

Hello,

Highlighting of Items is not working for me in IE8 when I hover over them.

From what I can tell, a RadComboBoxItem's css class is supposed to change from ComboBoxItem_Vista to ComboBoxItemHover_Vista when the user mouses over it. If I add a doctype declaration to my page, this behavior stops working in IE8. Only the first item that I mouse over gets the hover class. When I hover over other items, the highlight does not move. If I move the mouse away from the dropdown completely and return, the first item I hover over gets the hover class, but then when I move to other items, again, the highlight does not move.

Manually adding onmouseover and onmouseout attributes to each item when it is databound works, but slows the page down considerably because I have many items in each dropdown.

Here is a live sample: https://hertzequipus.rousesales.com/equipmentlisting.aspx

Here is the doctype declaration I am using:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

And I am using RadComboBox version 2.8.4.0.

Thank you for your help.

Selecting an item in Treeview inside a Combobox

I have a hierarchial TreeView inside a combo box. The basic functionality is fine except for the following scenario:
When the edit page is loaded we already know the value of a treeNode. When I click on the drop down button on the combobox,
as it is now, the treeview is displayed with all nodes closed.
I would like the tree view to expand to the proper level with the selected node highlighted. I tried doing this:
       _onClientDropDownOpening: function(sender, e)
        {
            var selectedNode = this._ObjectiveTypeTreeView.get_selectedNode();
            if (selectedNode != null)
            {
                selectedNode.scrollIntoView();
            }
        },
but it doesn't work. I would appreciate any pointers.
Thanks!

Wrong SelectedItems.Count()

Guys,
If I select 2 items in a list (using ctrl+ ) and then click (without CTRL) on one of those selected items visually it shows me that only one item is selected. Then I click on the asp:Button and in code-behind check SelectedItems.Count() it gives me 2 instead of 1.
Is there some work-around that will give me correct count, before this is fixed?

Thanks!

[Solved] how to span results accross multiple columns in grid

Want results of single column of values, say topics, the results would yield 50 records how do I show those results in multiple columns spanning accross the page. Show maximum of 10 results in first column and then 10 in 2nd and so on, spaced evenly accross the page with maximum of say 5 columns per page (5 columns 10 items each column) then in grid (set to 50 records) would have a next page to display records 51-100 ect...
