Hello,

I'm using XamDataGrid Version 12.2 and tryin' to achieve the same as above but your solution doesn't seem to work for me. There are two problems:

1) I have three Columns A, B, C with Fieldsettings.AllowEdit of B set to false. If I use right arrow to move from cell A to B, B is automatically skipped and focus is on cell C but it's not in edit mode because PreviewKeyDown-Event wasn't fired.

2) Cell value isn't selected in edit mode

Hello,

You can use the following code:

private void xamDataGrid1_PreviewKeyDown(object sender, KeyEventArgs e)
{
    if (!xamDataGrid1.ActiveCell.IsInEditMode)
    {
        return;
    }
    if (e.Key == Key.Left)
    {
        xamDataGrid1.ExecuteCommand(DataPresenterCommands.EndEditModeAndAcceptChanges);
        do
        {
            xamDataGrid1.ExecuteCommand(DataPresenterCommands.CellLeft);
        } 
        while (xamDataGrid1.ActiveCell.Field.Settings.AllowEdit == false);
        xamDataGrid1.ExecuteCommand(DataPresenterCommands.StartEditMode);
    }
    if (e.Key == Key.Right)
    {
        xamDataGrid1.ExecuteCommand(DataPresenterCommands.EndEditModeAndAcceptChanges);
        do
        {
            xamDataGrid1.ExecuteCommand(DataPresenterCommands.CellRight);
        } 
        while (xamDataGrid1.ActiveCell.Field.Settings.AllowEdit == false);  
        xamDataGrid1.ExecuteCommand(DataPresenterCommands.StartEditMode);
    }
    if (e.Key == Key.Up)
    {
        xamDataGrid1.ExecuteCommand(DataPresenterCommands.EndEditModeAndAcceptChanges);
        do
        {
            xamDataGrid1.ExecuteCommand(DataPresenterCommands.CellAbove);
        } 
        while (xamDataGrid1.ActiveCell.Field.Settings.AllowEdit == false);
        xamDataGrid1.ExecuteCommand(DataPresenterCommands.StartEditMode);
    }
    if (e.Key == Key.Down)
    {
        xamDataGrid1.ExecuteCommand(DataPresenterCommands.EndEditModeAndAcceptChanges);
        do
        {
            xamDataGrid1.ExecuteCommand(DataPresenterCommands.CellBelow);
        } 
        while (xamDataGrid1.ActiveCell.Field.Settings.AllowEdit == false);
        xamDataGrid1.ExecuteCommand(DataPresenterCommands.StartEditMode);
    }
}

Hope this helps you.

Works nearly perfect. But my problem No. 2 is not solved. The values don't get selected after getting focus.

Hello,

I can suggest you handle the XamDataGrid’s EditModeStarted event and add the following handler for it:

private void xamDataGrid1_EditModeStarted(object sender, Infragistics.Windows.DataPresenter.Events.EditModeStartedEventArgs e)
{
    Dispatcher.BeginInvoke(new Action(() => 
    {
        (Utilities.GetDescendantFromType(e.Editor as DependencyObject, typeof(TextBox), true) as TextBox).SelectAll();
    }), System.Windows.Threading.DispatcherPriority.Background, null);            
} 

Hope this helps you.

Now it's perfect, thank you very much!

Hi,

Do we have similar functionality for XamGrid as we are using that.

Thanks

Hello Soudip,

I have created a sample project for you where I implemented the same functionality for the XamGrid.

Hope this helps you.
