How can I scroll through the TreeViewAdv control using up/down arrow keys while in edit mode?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014


The user could navigate through the nodes in the TreeViewAdv control using the keyboard while in editing mode, by using the following code snippet:


private void treeViewAdv1_BeforeEdit(object sender, Syncfusion.Windows.Forms.Tools.TreeNodeAdvBeforeEditEventArgs e)



TextBox t=e.TextBox;

//To handle the Keys while editing the node

t.KeyDown+=new KeyEventHandler(t_KeyDown);


private void t_KeyDown(object sender, KeyEventArgs e)


TextBox t=sender as TextBox;



//To Stop the editing


//To replace the edited contents into the selected node.


//End the event





Private Sub treeViewAdv1_BeforeEdit(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.TreeNodeAdvBeforeEditEventArgs)


Dim t As TextBox=e.TextBox

'To handle the Keys while editing the node

AddHandler t.KeyDown, AddressOf t_KeyDown

End Sub

Private Sub t_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs)

Dim t As TextBox=CType(IIf(TypeOf sender Is TextBox, sender, Nothing), TextBox)

If e.KeyData=Keys.Down OrElse e.KeyData=Keys.Up Then

'To Stop the editing


'To replace the edited contents into the selected node.


'End the event


End If

End Sub
