I have a GridView bound using MVVM to a collection of `List<Person> People`.

Let's say the 'Person' class has properties like:

public List<ID> IDs { get; set; }

public string Name { get; set; }

public DateTime BirthDate { get; set; }

My issue is that I'd like to allow a user to click to insert a new row in the data grid, but I need it so that as they are typing in a 'Name', the DB is doing a query finding all IDs for that person which will populate a ComboBoxColumn for the IDs property above.  So it seems like I need to be able to bind (with MVVM) onto a 'Cell Editing' event for a cell so I can get an event as each character is typed.  I also need to know what item (SelectedItem is null for a new row for some reason in MVVM) is being edited so I can insert the returned array of found IDs into that item.  Any help would be appreciated and I'd like to avoid using Code-Behind.

Hi,

I'm using RadGridView in my wpf project, and the filtering mode for the gridview is "FilterRow". I have a column with datatype of DateTime.

I'd like to have a custom filtering for this column like the one you have in you sample called "CustomFilteringControl/FromDateToDateFilterControl".

But it doesn't work, and I still see the default pop-up window for that column.

My question is that :"Is there  a way to have "FilterRow" as the filtering mode and create custom filtering for each column at the same time?"

Thanks!

I have grid with 2 rows. I want to set first row Height base on how many lines are in RadTileView.

All items should be visible on screen (without scrollbars).

RadTileView items are moved automatically to next line if there is no place in current line.

How can i achieve that?

Sample code:

Hi,

if I'm trying to host your control, I will get an error that the component "Telerik.Windows.Documents.UI.Adorner.ImageAdornerUI" has no resource which could be identified by URI "/Telerik.Windows.Documents;component/ui/adorner/imageadornerui.xaml".

If I run it anyway, this result will be shown:

What I then did, is creating a new empty project and copied your sample which works.

If I copy that back I will get the exceptions.

I use R3 2017.

Any ideas?

Hi,

Following your documentation (number-formats) I'm trying to set a "# ##0" format to a cell to get a result like in the attached file 'Screenshot No1.png': 

But I get escaped space format "#\ ##0" in the resultant excel, like in the attached file "Screenshot No2.png"

How to get the exact result "# ##0" in the exported Excel file ?

Thanks

I'm using Telerik UI for WPF, R2 2018 SP1

GanttView has TreeColumnDefinition to display items that have parent/child relationship nicely, without extra header

Is there a way to use TreeColumnDefinition in RadGridView, since it's support sort, filter, context menu (which GanttView doesn't have).

I've browse over Seft-Referenced Hierarchical example, but all of them add an extra header to child item, and not support multiple hierarchical

Thanks in advanced

Hi,

can the pdfviewer automatically scroll in the position where the user is zooming with the fingers?

because if i zoom in a specific position (for example bottom right), the pdfviewer continues to zoom in top left angle of the pdf.

Thanks

Hi,

I can persist RadRibbonRadioButton selected state fine but it does not on restore execute the bound command. I'm trying to use the persistence manager to restore the UI, and as a result, restore the view model state.

Is this possible?
