It would be nice if we had 2 more events on the columns as well

TaskBoardColumnCollapsing, TaskBoardColumnCollapsed

These would be necessary when the control is database driven since the TaskBoardColumnCollapsed would trigger a database update for the TaskBoardColumns Table.

If it's already there... can you tell me how I can access that event?

The reason I'm finding a lot of these 'things' is because I have already converted the 'example code' into a relational database structure.
And as I'm working with the control - I'm getting stuck with trying to find the events that would trigger a database update.

Sorry, I'm not trying to be a pain....

To provide an example of the point I'm trying to make here.... I will provide the database schema for the table that I created for the Columns.

SELECT TOP (1000) [id]
      ,[Title]
      ,[Subtitle]
      ,[Collapsed]
      ,[OrderSequence]
  FROM [TaskBoard].[dbo].[TaskBoardColumnElements]

This is probably not the best name for the event - but it gives you the idea of what I'm looking to do.
Without such an event, we're not able to detect a change to the Collapsed State hence not able to update the database table accordingly.

The Event for the TaskBoardColumnCollapsed would be something like this;

Private Sub radTaskBoard1_TaskBoardColumnCollapsed()
Dim SQL As String = ""
Dim ColumnID As Integer = targetColumnElement.Tag  'The TaskBoardColumnElements.id of the target column

SQL = $"Update TaskBoardColumnElements SET Collapsed = {IIf(oRadColumn.IsCollapsed, 1, 0)} WHERE id = {TaskBoardColumnID}"

End Sub

Hello, Martin,

These events are available at RadTaskBoardColumnElement level. Please refer to the following code snippet:
        For Each columnElement As RadTaskBoardColumnElement In Me.RadTaskBoard1.Columns
            AddHandler columnElement.IsCollapsedChanging, AddressOf columnElement_IsCollapsedChanging
            AddHandler columnElement.IsCollapsedChanged, AddressOf columnElement_IsCollapsedChanged
        Next


    Private Sub columnElement_IsCollapsedChanged(sender As Object, e As EventArgs)

    End Sub

    Private Sub columnElement_IsCollapsedChanging(sender As Object, e As CancelEventArgs)

    End Sub

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
