I am attempting to use the ExpressionEditor to build an expression string for an object (building a custom template designer) pretty similar to the examples using it to filter data. The difference however is I'll have multiple tables/objects, and won't know which one I'll need till run time (I'll only build the string for one table/object like in the examples).

 I currently have the Item bound to an object, and that gets set after the user selected the object to build the string for. The object is getting set, but the Selected Category Items Pane is not getting refreshed after the object gets updated. I can set up to where the user selected the item on a previous screen, but would really like the list to be truly dynamic.

Item="{Binding BindingObject,NotifyOnSourceUpdated=True,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"

Basically, is there a way to refresh the Selected Category Items Pane, or a better way to bind the item dynamically?

Does anyone have a behavior or attached property that would enabled me to create GridViewDataColumn "templates" for all of the possible columns that are autogenerated from DataTable?  The ItemsSource is a DataTable that could have various different columns from a finite list of all potential columns.  I'd like to template every potential column.

Hi,
  I am working on dynamic loading of RadPanelBar Control. I am having a collections where 2 levels of topics would be there
The data would be in the below format
Id             Name             ParentCategoryID     LEVEL
19741         A                         19737                         1
19749         B                         19737                         1
19750         C                         19749                         2
19772         D                         19749                         2
19742         E                         19741                         2
19743         F                         19741                         2
19744         G                        19741                         2
I want to bind the Level 1 data in the parent level and Level 2 data with whose parentid matches with the id will be displayed as the child level
Eg) A and B are at the parent levels.
C,D will be displayed under B and E,F,G will be displayed under A
I created the following template to display this


I am getting the topics correctly and I was not able to filter the second level elements since the selecteditem for RadPanelBar always return null values(I'm using MVVM model). Also I was not able to expand the radpanelbar items in design. Should i need to add code for that? i want to expand the selected element. please respond me asap.

Is there a way to extend the DataFilter so that you can select how the Filtered Results get sorted from within the editor? Something like, Sort Ascending or Descending that shows up in the drop-down list.

Thanks,

Hello.

I have a simple wpf application based on the RadWindow which contains an UserControl. In the UserControl i have two controls: ListBox and RadScheduleView.  i used very good example from Telerik WPF Demos "RadScheduleView Drag And Drop" section. It works good when everything placed into a Window (or RadWindow). But when i am using UserControl instead of window and i am trying to drag some item from the ListBox i get exception: "Value cannot be null. Parameter name: second"

Stack Trace:

Hi,

Hi, I am trying to filter RadGridView in the background thread, to keep the UI active while user is typing his/her search string. All I am doing curretly is using custom predicate for all columns. With too many rows > 1K the UI get sluggish.


A

Does the TileView support grouping with a CollectionViewSource like how a ListBox does?
If it does can i get a sample?

Thanks

Hi,

Is it possible to have the GridView set to isBusy while a pasting operation is underway?  Sometimes it takes a few seconds to complete a large paste and it'd be nice to be able to have it show the user it is busy.  Thanks

Hi There,

we are planning to use "RADDataFilter" only as the UI to provide Search criteria and then use those criteria's as an input to sql procedure and search against the database. so to do this we need to get the criteria's entered by the user from DataFilter.
i checked properties of the DataFilter ,but could not get any which provides the information. 

Any help/comments would be appreciated.

Regards
Deepak
