I have a Business Object just like:

private class Employee
            {
            public int EmployeeID { get;set;}
            public int ManagerID { get;set;}
            public string Title {get;set;}

            public bool IsChecked { get; set; } = false;
    
            }

binding like this:

            List<Employee> employees = new List<Employee> {.......};

            radTreeView1.DataSource = employees;
            radTreeView1.DisplayMember = "Title";
            radTreeView1.ParentMember = "ManagerID";
            radTreeView1.ChildMember = "EmployeeID";
            radTreeView1.CheckedMember = "IsChecked";

when I toggle the tree node , the application throw an expection.

So,

what is the correct way to binding check-boxes on tristatemode ?

Hello,

Could you please help me with the following?

I have a listview containing multiple items, the listviewcontains SimpleListViewVisualItems.

Now I want to move items using DragDropService USING A TOUCHSCREEN (Gesture).

The functionality is working when I drag/drop using a mouse, within the list.

The functionality is working when I drag/drop using touchscreen to a second list, but when I am do drag/drop within the same list (using touchscreen), the PreviewDragOver and PreviewDragDrop events are not fired.

In my CustomRadListView, on the OnPanGesture-event I do call the dragDropService.DoMouseMove(mousep)

Best regards

Hello Experts,

Is there a way to not allow embedded images?

Allow first and remove after is also good but prevent in the first place is good 

Thnx

Hi,

Thanks,
Julian

I've attached a picture from an application that I'm trying to mimic, and I"m unsure how to do this with the GridView.

1) The ellipses lookup button on a column. Basically the same display functionality as the GridViewBrowseColumn, but rather than opening an OPenFileDialog, I want to open another WinForm that I'd pass data back and forth between.

 2) The alert icon in the column - alerting the user that there is some information to be displayed. 

Can anyone help by pointing me in the direction of a sample that has functionality like this, or offering some ideas on how best to accomplish? Currently, I have a command column that is performing the Lookup Function, but as the user moves columns around, it may not be in the correct place, so I don't think that's the correct path. 

     hi telerik

i'm use Telerik themes "Fluent" and "FluentDark" in my project. with a "ToggleSwitcher" and below code, change my project theme at runtime without any issue.

but, most controls like button, have image. in "Fluent" i'm use Black image, and must use White image in "FluentDark" theme. Now, have any solution to change all (maybe 100 Controls) image/icon at runtime? or have any solution for switch iamge between Dark and Light theme?
