RadGrid with undefined columns with FilterExpression

I found it difficult to title this appropriately, but here's my problem, first with some background info.

1. I created a DataTable, gave it some columns, and populated it with data.
2. I then used a DataView to sort that data.
3. Finally I bound the DataView to a custom control inheriting from RadGrid.

I want to filter the resulting RadGrid rows to divide it up into subsets, but no matter what I try for my FilterExpression, nothing works. After stepping through my code in debug mode, I noticed the RadGrid.Columns.Count = 0, even though I have results and columns with headers as I defined in my DataTable. I suspect this is why my FilterExpression is not working, though I also don't understand how it could have zero columns, yet the Columns are rendering just fine, headers and all. I was under the impression that by Binding my data, the RadGrid would automatically inherit the Columns and their names, but apparently not. How then can FilterExpression even work as it should?

Thoughts? Suggestions?

Sorting in header columns in Combobox.

I have implemented "combobox with grid-like multiple columns with headers" as in http://demos.telerik.com/aspnet-ajax/combobox/examples/default/defaultcs.aspx

If I have Product and quantity as two headers in the combobox,can I sort the records on clicking the column headers product and quantity(as in RadGrid)?

rad checkbox

Hi,

I don't currenlty have paid support so am posting this here. I would like to see a RadCheckBox control. This would have tri-state support so that true, false and null could be bound to it. There seems to be one in the treeview, but no stand-alone control.

FacebookShare Button

Is there an issues with the RadFacebookButton ButtonType="FacebookShare" or has Facebook phased this button type out. I noticed that it is not showing up in the SocialShare / Standard third party buttons demo. If Facebook has phased this button type out what is the new button type I should be using?
Thanks

In "Edit Mode" this is what I see...

http://postimage.org/image/4dlvnyep1/

Which is all correct and working as expected
What I need to happen is this, turn the dropdowns into google suggest like combos
So end users can type the first characters of an package name and it shows the matches
This is exactly what I am trying to do ... http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/comboingrid/defaultvb.aspx?product=combobox

but the data for my dropdown would be coming from another table which is not like this example

How can I modify it so the combobox uses the lookup table instead of the main datasource?

DropDownList Error when in Multi-Line Edit Mode

I have a requirement to have Grid where all the rows can be edited. I have the Grid opening with the Rows in Editmode. However, one of the columns is a DropDownList. We are doing the databind to the datasource for the drop down inside the ItemDataBound Event of the Grid. On the first Row, the dropdown works fine However, for anything other than the first row being edited, it shows the Type of the Datasource, and not the values. (See attached image)

Inside the ItemDataBound:

if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

GridEditManager editMan = editedItem.EditManager;

// Drop down for Status

GridDropDownListColumnEditor editor = editMan.GetColumnEditor("PStatusID") as GridDropDownListColumnEditor;

editor.DataSource = pStatuses;

editor.DataTextField = "Name";

editor.DataValueField = "PStatusID";

editor.DataBind();

}

This is the Column definition:
