The ctrl-tab and shift-ctrl-tab still work as designed. For benefit of lurkers ( and me when I forget what I did ) : When using a TabControl and multiple pages, you can tab from last control on page1 to first control on page2 by using the Leave event of the page1 control to set the SelectedTab() of the TabControl to page2 and then, in the Enter of page2 set the focus to the next control in the tab sequence.

Then I rearranged the form Tab order, and set the GroupBox "TabOrder on TabOrderController1" to 2, or whatever gets in the middle of the other 2 controls before and afterhand. Next, I added code to the GroupBox_Enter event to move the focus to the grid: Private Sub GroupBox1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) _ Handles GroupBox1.Enter '-- move focus to grid Me.grdCustomers.Focus() End Sub And, for the Grid "TabOrder on TabOrderController1", I set -1, so it will tab inside it freely. Hope it helps. Attachments UltraGridSample-CHRMod.zip (151 views, 143.00 KB)

Getting it to do exactly what I want has been a challenge, but so far I am managing to do it. "Someone" has always told me how working with grids was a pain in the neck... I will have a look at your sample and see if I can come back with some idea.

Group: Forum Members Posts: 524, Visits: 30K	Hi Ivan I've been working a lot using your ultraWingrid subclassing example. First, in order to exit the grid using Ctrl - Tab : If e.KeyCode = Windows.Forms.Keys.Tab AndAlso e.Control Then SetFocusToNextControl(True) End If If e.KeyCode = Windows.Forms.Keys.Tab AndAlso e.Control AndAlso e.Shift Then SetFocusToNextControl(False) End If If e.KeyCode = windows.Forms.Keys.Delete andalso e.Control then Me.currentActiveRow.Delete() End If MyBase.OnKeyDown(e) But the weird thing I have discovered is that if you use a SF TabOrderController on the form the tab in the grid will move to the next control (just as ctrl-tab does in the example above) and not tab you through the grid and into add record at the end. I've made minor mods to your sample to demonstrate both of these things. As delivered, you'll see tabbing from country into the grid and then tabbing moves through the grid until you exit with either Ctrl-Tab or Ctrl-Shift-Tab. But now drop a SF TabOrderController on the form, set the properties for the three controls and notice tabbing when in the grid moves your to postal code. Obviously, what we need is a way to tell the TabOrderController to ignore the Tab if the container is an ultrawingrid. Any ideas? Attachments UltraGridSample-CRHMod.zip (143 views, 142.00 KB)

Group: StrataFrame MVPs Posts: 1.9K, Visits: 21K	Hi Charles. SetFocustonextControl(true) is an UltraGrid method, so it will work fine inside an inherited UltraGrid. But then, you want to use Ctrl+Tab to exit the UltraGrid, which I agree is the easier thing for the user to understand, but I wasn't able to catch the keydown Ctrl+Tab from inside the UltraGrid. In order to do that, I used my BaseForm and added the following code: Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, _ ByVal keyData As System.Windows.Forms.Keys) As Boolean '-- check for unique keystrokes Select Case keyData Case Keys.Control Or Keys.Tab '-- created to be able to tab out of a Grid control Me.SelectNextControl(Me.ActiveControl, True, True, True, True) End Select Return MyBase.ProcessCmdKey(msg, keyData) End Function This worked fine for me, since all forms will tab to next control once the user types Ctrl+Tab. Regarding the Subs, they are overriding the grid's OnKeyDown (which we don't need anymore since we are testing the ProcessCmdKey in our base form) and OnEnter subs. That is why we call the MyBase.OnEnter(e) (remember DODEFAULT()? ) Thanks for the question, I wanted to write these features for myself as well.

Group: Forum Members Posts: 524, Visits: 30K	Sorry. I'm being a little stupid. i tried putting this in my subclass Imports Infragistics Imports Infragistics.Shared Imports System.Windows.Forms Public Class uWingrid Inherits Infragistics.Win.UltraWinGrid.UltraGrid Public Sub New() Me.DisplayLayout.CaptionVisible = Win.DefaultableBoolean.False Me.DisplayLayout.GroupByBox.Hidden = True Me.DisplayLayout.Override.AllowAddNew = Infragistics.Win.UltraWinGrid.AllowAddNew.FixedAddRowOnBottom Me.DisplayLayout.Override.AllowDelete = Infragistics.Win.DefaultableBoolean.[True] Me.DisplayLayout.Override.AllowRowSummaries = Infragistics.Win.UltraWinGrid.AllowRowSummaries.[False] Me.DisplayLayout.Override.AllowUpdate = Infragistics.Win.DefaultableBoolean.[True] End Sub Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs) If e.KeyCode = Keys.E AndAlso e.Control Then SetFocusToNextControl(True) End If MyBase.OnKeyDown(e) End Sub Protected Overrides Sub OnEnter(ByVal e As System.EventArgs) Me.PerformAction(Infragistics.Win.UltraWinGrid.UltraGridAction.ActivateCell) Me.PerformAction(Infragistics.Win.UltraWinGrid.UltraGridAction.EnterEditMode) MyBase.OnEnter(e) End Sub End Class The two sub don't seem to be event handlers and they don't appear to be being called. If I have a form with 13 ultragrids, where would I put the subs ? Or f I wanted this behavior for a single grid? It looks like the code should be in a subclass, but I think I'm missing something about subclassing the grid ....? I guess my brain isn't working today.
