hi,

i want to use the radvirtualgrid to add a new row/record to a database but instead of using Tab button to switch between column i prefer to use the enter key.

is that possible, if yes can you give me a sample please ?

Thanks in advance

I have to add a context menu to the list view but need the menu items to change depending on the items clicked, but am not able to find the contextmenuopening event for the listbox. am i missing something or is there a different way to handle this.
I have used this same method for treeview and that works perfectly.

As the title suggest, how can I deselect currently selected row if it's previously selected? I have MultiSelect set to False. Ctrl + click doesn't work.

I have a RadAutoCompleteBox working as expected allowing user to type and pick an item from the list.

The token is then shown in the Textbox as expected.

 

Would like to have a way when they type again and pick another item, to then remove the 1st and only show the 2nd item.

Tried the  radautocompletebox.Text = "" but received some error.  It would be nice to have a property stating (Multiple Tokens (true/false).

 

Maybe there is a programmatically way to click the X in the token to remove it before adding the 2nd token?

Hello,

I am working an application where I need to open the different application forms in the same main window; in other words, I have created a dashboard where it contains a several buttons, each of them should open a specific form for example, The Employees, Products, Tasks, and etc. when I click on each of the buttons, It should show the other forms but in the same RAD form.

Form.TopLevel = False property isn't working so, How can I do it?

My project is a VB.NET 2019.

Thanks in advance for your continues assistance and cooperation,

Hani Mansour

Hi.

After a date is picked I want to delete it and set the value to null on the data bound item.

The NullableValue is set to null/Nothing:

 Me.DateRadDateTimePicker.NullableValue = Nothing

The Value property is bound to an entity's nullable date field:

 Me.DateRadDateTimePicker.DataBindings.Add(New System.Windows.Forms.Binding("Value", Me.binder, "Date", True))

If I select the date text and delete it, the entity still has a 01/01/0001 date value. However, the null text correctly displays in the picker.

I've even tried to manually set the null date (in three different ways!) based on the empty text but to no avail:


Dim dtp As RadDateTimePicker = ctrl
If dtp.Text = "" Then
  dtp.NullableValue = Nothing
  dtp.DateTimePickerElement.SetToNullValue()
  dtp.Value = Nothing
End If

 

What am I missing?

I'm getting the following error every time I load any project in VS 2019 (16.9.4)

"Visual Studio stopped responding for 12 seconds.  Disabling the extension Progress Telerik WinForms Converter 2021.2.505.1 might help."

See attached image of error.

How to resolve?

Cheers, Rob.

EDIT: for any project, WPF, UWP, etc. (not just WinForms)
