Hi
How To RightToLeft RadAlarmForm when Shown Appointment Alarm?

Hi,

I'm trying to change the border color on a RadTextBox.
It should be easy using the control, but in my case the radtextbox is stored in a var.
Here a sample

 

Dim controle As String = CType(sender, RadTextBox).Name

 ' Change the text : It works !

Controls(controle).Text = "Hello, World"

 ' Change the border = DON'T WORK

DirectCast(Me.Controls(controle).TextBoxElement.Children(2), Telerik.WinControls.Primitives.BorderPrimitive).ForeColor = Color.Red

 

So I can change the text, but I have a problem with this line (.textBoxElement) not present :

DirectCast

 

 

Me.controls(controle).TextBoxElement.Children(2), Telerik.WinControls.Primitives.BorderPrimitive).ForeColor = Color.Red

Thanks for your help

I closed a couple of document windows in my Dock to free up space to work in visual studio.
I assumed that those windows would not have been permanently deleted, but they appear
to be gone.  When I re-enter the advanced designer, I no longer see them.

Is there a way to recover or restore those document windows I had closed in the advanced
designer of the Dock?

Hello everyone,
I've been using Telerik's aspx AJAX controls for a while now and I just started to review their winforms controls for a legacy project. I've read through the online documentation for the GridView and I'm still struggling to bind my data successfully. Here's my structure.

Rooms
- Products
- - Related Products

I need each level to be capable of drag and drop to other controls in the application so it appears that I need a total of three templates (two in addition to the master). In my testing I've been manually databinding the grid and I've managed to load my rooms when the form loads. I've then chosen to use the "MasterTemplate_RowSourceNeeded" to load my first level products when a room is expanded (which works as expected). Now I'm struggling to add the final level (Related Products). I've tried adding a Related Products template at runtime when the Products level is being filled (no issues here). I then added a relationship to the gridview to relate the products with their related products and while this doesn't produce an error the Related Products aren't visible in the gridview. I then tried manually creating each Related Product row within the related template using a dataview's filter to get the related products. Again this ran without error but clicking the drop arrow next to the Product only changes the drop arrow to the opened state with no Related Products being shown. I've tried to watch a handful of the databinding videos on Telerik's website but the video doesn't show (like a white box is over the video).

Any help is greatly appreciated :)

Does anyone know how do I set a particular value in a cell radgridview?

For example: 

if ((bool)e.CellElement.RowInfo.Cells["Arquivado"].Value == true)
                        {
                            e.CellElement.Text = "Sim";
or
    e.CellElement.Value = "Sim";
or
    e.CellElement.RowInfo.Cells["Arquivado"].Value = "Sim";
                        }

Thanks;

Hi, 

I have a RadListview on a form connected to a datasource. Then I have a timer which call a method that refreshs the content of the DataTable periodically.  After starting it shows the content correctly. But as soon as the DataTable is refreshed for the first time I ran into problems. 

The RadListView itself seems not to recognize when the underlying DataTable is changing. That's no problem so I have to tell the RadListView to refresh. My first try was the Refresh() Method. That seemed not to work. So I've tried to reassign the DataTable to the RadListView in setting it again as DataSource. This will throw an exception that a column is not contained in the table (more precisely it's the first column). Looking in to the underlying DataTable the column is included.

Wrapping the commands into BeginUpdate() and EndUpdate() makes no change.

Surely I have something overlooked to make it work. Any help is welcome.

Is there a way using only the RadGridView control to show more than 2 custom filtering conditions?

The attached image shows an example of the RadGridView filter dialog.

Thanks for any help.

Hello!

I have a custom VisualItem "CustomVisualItem : IconListViewVisualItem" which belongs to a ListView with ViewType=IconsView.
The VisualItem consits of a StackLayoutPanel with 2 LightVisualElements (one is displaying a image and the other displays text).
The Datasource for the ListView is "List<CustomClass>".

Now I want to achieve the following:
- check if VisualItem is Databound to CustomClass
- when property "Disabled" of CustomClass is true then draw a red X over the VisualItem (a red line from Top-Left to Bottom-Right and one from Top-Right to Bottom-Left)

This is my current not working solution:

How can I place the red X (or the rectangle) over the VisuaItem?
