Hi I am using a multiselect radcombobox where i am binding the data dynamically at code behind. There is a rad button too on the page.

Please suggest is there any way to get CheckedItems.count when data is binding dynamically at code behind.

[Solved] Grouped grid datasource, neither a DataColumn nor a DataRelation

Hi
I am converting to the latest controls and I am getting the following runtime error:

intKey is neither a DataColumn nor a DataRelation for table GroupedTable0.

This code is currently working with version 2010.3.1109 of controls. The data for the grouped grid is coming from a stored procedure via a strongly types data adapter (i.e. dataset). I am applying a filter on the data, prior to manually binding the grid. When I bind the grid I get the above exception.
I have added a intKey column with visibility set to false to the columns collection but that did not help.

[Solved] DataBinding Drop Down Tree

I can't seem to bind data to a drop down tree.

Markup:

<telerik:RadDropDownTree runat="server" ID="radGrades" DefaultMessage="Grade"></telerik:RadDropDownTree>

Code Behind:

RadDropDownTree gradeTree = item.FindControl("radGrades") as RadDropDownTree;

var grades = Grade.GetVGradeTypes(); //returns List<v_grade_type>, 6 items in list

gradeTree.Entries.Clear();

gradeTree.DataFieldID = "grade_id";

gradeTree.DataFieldParentID = "grade_type_id";

gradeTree.DataTextField = "grade";

gradeTree.DataSource = grades;

gradeTree.DataBind();

I should also note, this is being called from the "ItemDataBound" event on a RadGrid [adding a new item, haven't looked at editing an existing item]. The markup lives in the EditFormTemplate of the grid.
Any ideas?

Custom paging

Hello!

I can't seem to find a way to implement custom paging in the RadFileExplorer control. I have created my own ContentProvider and I have tried to enable custom paging on the internal grid, but no paging events seems to occur. I really need custom paging since our database contains a lots of object and I don't want to retrieve all of them at once (some folders even time out).

Is there a way to do this or must I create my own FileExplorer?

Best regards,
Patrik Edberg
