WinForms Gantt View - date input format

[Jacek]

Hi,
When modifying the value in the column, eg "Start", I need the control that supports entering the date to be displayed in the ShortDateString mode.
I tried to capture a control in the ControlAdded event, but I am capturing the HostedTextBoxBase, not the DateTimePicker.

 

    Private Sub RadGanttView1_ControlAdded(sender As Object, e As ControlEventArgs) Handles RadGanttView1.ControlAdded
        Dim startDate As Date = RadGanttView1.SelectedItem.Start
        e.Control.ResetText()
        e.Control.Text = startDate.ToShortDateString
    End Sub

How can I change the date input format to Short?

Regards
Jack

Hello Jacek,

Thank you for the provided code snippet.

To change the date format of a specific column, you can set the FormatString property of this column. For example, you can get all columns in the Columns collection property of the RadGanttView. Then you just set the date format as per your requirement. The following code snippet demonstrates this. On my side, the Start column is the first column. 

this.radGanttView1.Columns[0].FormatString = "{0:MM / dd / yyyy}";

I hope this approach will work for you.

Hi Dinko
Thanks for your code.

I found a solution:

Public Sub New()

'Add handler
        AddHandler Me.RadGanttView1.GanttViewElement.EditorInitialized, AddressOf editorInit

End Sub

Sub editorInit(sender As Object, e As GanttViewItemEditorInitializedEventArgs)
        Dim dtEditor As GanttViewDateTimeEditor = TryCast(e.Editor, GanttViewDateTimeEditor)
        If dtEditor IsNot Nothing Then
            dtEditor.CustomFormat = "dd/MM/yyyy"
         End If
    End Sub
