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


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
