Hi Guyz,

I am not able to set the focus to another tabitem with in a TabControl. Some times focus works; but most of the time not working. The code is 

 private void dgClmPaymentScheduleInstallment_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            DependencyObject source = e.OriginalSource as DependencyObject;
            if (source == null)
                return;
            DataRecordPresenter drp = Infragistics.Windows.Utilities.GetAncestorFromType(source,
                    typeof(DataRecordPresenter), true) as DataRecordPresenter;
            if (drp == null)
                return;
            if (drp.Record != null)
            {
                drp.Record.IsSelected = true;
                drp.IsActive = true;
                DataRecord myRecord = drp.DataRecord;
                if (myRecord.ParentRecord == null)
                {
                    LoadDataForEditingPaymentTemplate();
                   // tabPaymentScheduleTemplate.Focus();
                    //Keyboard.Focus(tabPaymentScheduleTemplate);
                }
                else
                {
                    window.comPricingElementID = (int)myRecord.Cells["COMPricingElementID"].Value;
                    LoadDataForEditingPaymentSchedule(window.paymentInstallmentID);
                }
            }
        }

Most of the time any of the three focus codes not working. I tried all the three focus codes independently. 

What's wrong?

 Thanks
