I am trying to add a new item to the GridView. When the user tabs past the last column of the last row I'm inserting a new row and placing it in edit mode. I do this by handling the KeyDown event like this:

        private void RadGridView_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Key == Key.Tab)
            {
                var grid = sender as RadGridView;
                var currentItem = grid.CurrentItem as OrderDetail;
                if ((currentItem != null) && (currentItem.IsValid))
                {
                    grid.BeginInsert();
                    grid.CurrentColumn = grid.Columns[0];
                }
                else
                {
                    e.Handled = true;
                }
            }
        }

I also handle the AddingNewDataItem event to add a new object:

        private void RadGridView_AddingNewDataItem(object sender, Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs e)
        {
            e.NewObject = OrderDetail.NewOrderDetail();
        }

The problem is that I need the new object to be added to the underlying collection that is bound to the ItemsSource property of the GridView so that a number of event handlers can be hooked up to events on the OrderDetail object. (These events bubble up list / property change notifications to the parent Order object for such things as calculating the Order total, sales tax, etc.).

The new row is being added and it gets set into edit mode but when I modify data in the columns for Quantity and UnitPrice no events are being published because the OrderDetail object is not inserted into the collection (which does the job of hooking up the events).

I tried to add the object to the collection but then I get two new rows added to the GridView. What I would like to do is add the OrderDetail to the underlying collection so that event handlers get hooked up but then set the row into edit mode on the first column. Is this possible or is there some other way to approach this?

Thanks,
Dave

Hello Telerik,

I'm trying to put an TileView in a BusyIndicator but the tileview doesn't appear.

Do you have a sample code to do this ?

Thank you.

Hello, 

I can't ever seem to get the vertical scroll to appear. The regular MS Windows grid scrolls always appears. This control is being added to another grid inside a RadTabItem. I would like the scroll to kick in when ever the screen size requires it without having to set hard Heights and Widths. Thanks.

Hi,

I'm trying to implement filter search in the grid

This is the code:

 

 

private void OnFilterByTextCommand(string parameter)
  {
   var compositeDescriptor = new CompositeFilterDescriptor
                              {
                               LogicalOperator = FilterCompositionLogicalOperator.Or
                              };
   
  
   
   foreach (GridViewColumn column in RadGrid.Columns)   
   {
    var dataColumn = column as GridViewDataColumn;
    if (column == null) continue;
    
    object obj = null;
    
    try
    {
     if (dataColumn != null)
       obj = Convert.ChangeType(parameter, dataColumn.DataType);
    }
    catch
    {
     continue;
    }
    if (obj == null) continue;

    FilterOperator op = dataColumn.DataType.IsValueType ? FilterOperator.IsEqualTo : FilterOperator.Contains;
    

    FilterDescriptor filterDescriptor = new FilterDescriptor
                                         {
                                          IsCaseSensitive = false,
               Member = dataColumn.UniqueName,
               Operator=op,
               Value=obj
                                         };
   
    compositeDescriptor.FilterDescriptors.Add(filterDescriptor);
   
   
   }
   
   RadGrid.FilterDescriptors.Add(compositeDescriptor);
     
  }

I get exception in the columns that the column type is not the same as the

Item source collection in this binding member

If I bind the column to same data type and us one of this data properties

The exception is cant cast beaten the types

Someone know this problem?

Maybe I need to change the filter method?

Best Regards

Hi,

Simply running your Q1 2010 demo for the wpf docking does not work correctly with my multiple monitor configuration. I currently am running Windows 7 and have 3 monitors set-up to extend my desktop. One of my monitors is plugged into a usb video port replicator docking port which is where the problem occurs. My configuration is my center screen is my primary, then I have a screen to the left and another one to the right. If I drag a window to the right it works as expected. I am unable to drag to the left, simply does not recognize the boundries or something. If I run the whole application on the left monitor and try to undock a window, the undocked window just vanishes, not even letting me drag it around. The docking port I use is the HP HSTNN-S01x. Currently I use the Actipro docking control and do not encounter this issue.

Thanks

Rick

Hi, all

 Nice to meet you!

Hello,
I have a problem with using ShowDialog method of RadWindow in WebBrowser. A new window appears, but ShowDialog should susspend by main application. I use Close callback to resolve this problem, but it's not a good solution for complicated application.
I really need to freeze code execution when modal dialog appears.

Hi,

searching the internet I found following statement:

Q: Can I use Bing Maps (Virtual Earth) within a Windows Forms or WPF Desktop Application?

A: As far as Licensing, you’ll need to contact Microsoft. The “Microsoft Virtual Earth Platform API Terms of Use” doesn’t really cover this specific usage scenario.

Microsoft doesn’t have a Window Forms or WPF control that you can just drag onto a Window, but you could access the Web Service from your application or display the JavaScript Map Control within an embedded WebBrowser control.

(http://pietschsoft.com/post/2009/06/02/Bing-Maps-for-Enterprise-Virtual-Earth-Licensing-FAQ-Questions.aspx)

Do I really have to contact Microsoft for using RadMap or do you already know which licensing-model is needed for commercial use of your control?

Best Regards
Steffen
