Hello Curtis,

                    We want to select context menu at run time depending upon type of the record on which the Mouse rightClick event occured . i.e. if there are two levels of records in the Datapresenter e.g. First row contains Order and rows following to it contains Products in the Order.

                   I have 2 Context Menus, one for Orders and second for Products.

                    Suppose when I right click on Order Record (Row) then I need to show the context menu for Orders and when I Right Click on any of the Product record which belongs to any of the Order record then I need to show context menu for Products.

                   The problem which we are facing is that before right clicking on any record, we are supposed to first left click on it , make it as Activerecord and the we need to right click on it so that we can identify the records (whether it is order record or product record ) at runtime and decide which context menu we should show Up.

                   Here is some code for Right Click event

 private void DataPresenter_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
        {

            DataRecord drCurrent = (DataRecord)DataPresenter.ActiveRecord;
          

              if(drCurrent.Cells[0].Value =="Product")

            DataPresenter.ContextMenu = ProductContextMenu;

              else

            DataPresenter.ContextMenu = OrderContextMenu;

        }

                The expected behaviour is that when we RightClick on any record of Datapresenter, the record should become Activerecord of the Datapresenter (instead of first left click on the record, make it activeRedord and then Right click on the same record).

Please let us know whether we are missing any event of Datapresenter which provides expected functionality.

Thanks,

Chetan Deshmukh       

Thanks Curtis

      One question : Is the above solution applicable for both xamDataGrid and XamDataPresenter...?                 

Done

          Here is some code i would like to share with You....

 void AssetGrid_PreviewMouseRightButtonDown(object sender, MouseButtonEventArgs e)
        {
        //    VisualTreeHelper.HitTest(dw.ucAssetGrid.AssetGrid, null, HitTestResultFunc, new
        //    PointHitTestParameters(e.GetPosition(dw.ucAssetGrid.AssetGrid)));
            RightClickReturn = true;
            VisualTreeHelper.HitTest(dw.ucAssetGrid.AssetGrid, HitTestFilterFunc,
             HitTestResultFunc, new
             PointHitTestParameters(e.GetPosition((UIElement)sender)));

        }

        public HitTestResultBehavior HitTestResultFunc(HitTestResult result)
        {
            DependencyObject dobj = result.VisualHit;
            // lbxResult.Items.Add(dobj.GetType().Name);
            //MessageBox.Show(VisualTreeHelper.GetParent(dobj).GetType().ToString());

            if (RightClickReturn ==true && VisualTreeHelper.GetParent(dobj).GetType().ToString() =="Infragistics.Windows.DataPresenter.DataRecordPresenter")
            {
                DataRecordPresenter rp = (DataRecordPresenter)VisualTreeHelper.GetParent(dobj);
                dw.ucAssetGrid.AssetGrid.SelectedItems.Records.Clear();   
                rp.Record.IsSelected = true;
                rp.Record.IsActive = true;
                RightClickReturn = false;
               // return ;
            }
            return HitTestResultBehavior.Continue;
        }

        public HitTestFilterBehavior HitTestFilterFunc(DependencyObject
        potentialHitTestTarget)
        {
            //lbxResult.Items.Add(potentialHitTestTarget.GetType().Name);
            return HitTestFilterBehavior.Continue;
        }

          The above code is working as per expected.

Thanks,

Thanks for posting your solution Chetan! Excellent Work!

Hi Curtis,

  Good morning [:)]

           I experienced that if we use DatagridView of System.Windows.Forms and Images in XBAP application then we need to set the application in Full trust mode and for that we need certificates at client side.

           I have tested a sample XBAP application with Infragistic control and it worked well in partial trust. Is there any known issue in Infragistic which need the XBAP application to be in full trust only....?  

           I do not want to use any certificates for my XBAP application which require to have certificates at client side. 

           Also can we use images in our XBAP application which is in partial trust..?

Hi Custis,

As we discussed, sharing the solution of the problem mentioned above by me..

Problem inshort: When we bind any object(which is not a string) to DataGrid field, the field not remains sortable.

Solution: Create an UnBound Field and set Binding to it as follows.

<InfraGrid:UnboundField BindingPath="[ObjectName].[PropertyName]" Label="Preferred Description" Width="480">

 In my case I had a Colloection as a datasource. The collection was of class which has a field of type RecordType. When I bind the colloection to a DataGrid, RecordType field gets assigned to one of the fields. As I override ToString method of RecordType class and returned RecordName, I could see the RecordNames in the field but cound not sort the field. When I used Unbound field and explicitely set the BindingPath to the RecordName, I cound see the RecordNames in the field as well as could sort the field. 

Hello Chetan,

I received your sample. I will get back to you as soon as I determine what the problem is and will communicate the solution here for other users as well.

Thank you!

Hi Custis,

I tried following but not working.

 EditAsType="{x:Type Sys:String}" on FieldSettings

can I try anything else to solve the issue?

Hi Curtis,

Sent you an email with the sample application attached.

Please let me know if you need more details about the issue.

Thanks,

Chetan

You may need to explicitly set the type to string in the Field Settings. If you could replicate the issue in a smaller sample project, I could better determine why sorting isn't working and correct the problem.

Thank you!
