Hi,
Is it possible to include a 'Contains' filtering condition for columns with DateTime data type (See attachment). We need this to allow our users to filter records based on a particular month. The date time format we're using is dd/MM/yyyy.
Thanks in advanced.

I have a grid view sorted by a date column, users can add records to the grid view via the "Click here to add new item" row, a context menu, or ribbon button. All the non-grid view method just call the BeginInsert method of the grid view which seems to work without issue. I would like to automatically set the inserted row as the selected row of the grid view when the insert is complete. To do this I am using edit complete handler bellow:
| private void crashRowEditComplete(object sender, GridViewRowEditEndedEventArgs e) |
| { |
| if (e.EditAction == GridViewEditAction.Commit |
| && e.EditOperationType == GridViewEditOperationType.Insert) |
| { |
| ApplicationState.Carrier.Crashes.Add((Crash)e.NewData); |
| ApplicationState.Carrier.Drivers.Add(((Crash)e.NewData).Driver); |
| ApplicationState.Carrier.Vehicles.Add(((Crash)e.NewData).Vehicle); |
| crashListGrid.SelectedItem = e.NewData; |
| } |
| } |
The handler is running fine (checked through debug and the fact that the data does get written out to the file - dependent on the three Add statements), but the item is not getting selected correctly. Instead the first row in the grid always gets selected. This seemed like a pretty simple requirement and I have manipulated the grid selection previously without issue.

Hello,
My company is evaluating the RadGridView for use in a project with a final delivery date in October, with an upcoming checkpoint next month. I have been unable to find any documentation of support for the 4.0 CLR. We are committed to EF4, so that is a requirement.
I have used the control in our 4.0 project with reasonable success, but I am seeing some discrepancies between the way the control works in Blend and in the project.
Do you support this control in 4.0 projects? When will it be supported in that environment? Is there a list of known issues workarounds in that environment?
Thanks!

Hi,
WPF Q1 2010 - Win XP SP3
When I
1. Dynamically create a pane containing a grid and move it to document host (NO other panes open).
2. Drag it so it is floating.
3. Dock it.
4. Unpin so auto hide kicks in.
5. Mouse over so the window slides out.
- Problem - when mouse leaves the area of the slided-out pane, it does not hide again.
6. If I open another pane and move it to the document host, now the original page behaves correctly (hiding and so on).
7. Close the second pane (the one docked in the document host) and the original pane contiues to behave correctly now (hiding nd so on).
Also, are the docking controls getting slow and clunky now or is it me ?
Any Ideas,
Thanks
Rob

Why doesn't this work?
| /// <summary> |
| /// Satisfies req for IPartnerMessenger. Dynamically Loads Partner radtab content. |
| /// </summary> |
| /// <param name="PartnerType"></param> |
| /// <param name="partner"></param> |
| public void NotifyPartnerSelection(Type PartnerType, Partner partner) |
| { |
| if (PartnerType == typeof(EmailPartner)) |
| { |
| this._selectedPartner = (EmailPartner)partner; |
| this.PartnerRadTabItem.SetValue(RadTabItem.ContentProperty, new EmailPartnerView(this, (EmailPartner)partner)); |
| } |
| else if (PartnerType == typeof(NamedCallPartner)) |
| { |
| this._selectedPartner = (NamedCallPartner)partner; |
| this.PartnerRadTabItem.SetValue(RadTabItem.ContentProperty, new NamedCallPartnerView(this, (NamedCallPartner)partner)); |
| } |
| else if (PartnerType == typeof(AnonymousCallPartner)) |
| { |
| this._selectedPartner = (AnonymousCallPartner)partner; |
| this.PartnerRadTabItem.SetValue(RadTabItem.ContentProperty, new AnonymousCallPartnerView(this, (AnonymousCallPartner)partner)); |
| } |
| else |
| ClientErrorHelper.ShowError(new Exception("Stuff went wrong")); |
| } |
I have tried it as just setting the content property directly as well. Basically it works for the first assignment to the content property and then all other setting attempts although the radtabitem.content property changes, the user control displayed in the tab does not change.

I’m using a generic item wrapper defined as below:
public class ItemWrapper
{
public State State { get; set; }
public string Message { get; set; }
public object Item { get; set; }
}
public enum State
{
Ok,
Warning,
Error
}
The ItemWrapper could contain objects from different classes in the Item property; for instance:
ItemWrapper wrapper = new ItemWrapper();
wrapper.Item = new Company() {Id = "Acme", Desc="Acme company" };
The point is how to bind RadGridView columns to show both ItemWrapper columns (State and Message) and wrapped object columns ( Company.Id and Company.Desc).
Binding ItemWrapper properties is ok while the expected way for Company should be:
col.DataMemberBinding = new Binding("Item.Id");
col.DataType = typeof(string);
that seems, at least, to work but raising lot of exceptions:
A first chance exception of type 'System.ArgumentException' occurred in Telerik.Windows.Data.dll
that slow down rows loading to several second for few items (making control unusable) .
Sincerely

I need to be able to filter the RadGridView based on a collection property on each item. Here is a sample to illustrate my case. Let’s suppose that each item in the grid is of type Person and each person has a collection property ScheduledMeetings. I need to apply some kind of filter that does the following:
People.Where(p => p. ScheduledMeetings.Contains(someMeeting))
which will return all people participating in the specified meeting.
The documentation samples all use the built-in CreateFilterExpression method of the FilterDescriptor class. So my first choice was to use the existing FilterDescriptor class in combination with FilterOperator.Contains but it seems that ‘Contains’ only works with strings and not with IEnumerable (even with FilterDescriptor.MemberType specified)!
I suppose I need to implement some custom FilterDescriptor class inheriting from FilterDescriptorBase and then provide the Expression from the CreateFilterExpression override. But how do I create such expression?

Hello,
I'm playing around with the Slider control and im trying to find a way to customize it. Basically all I'm looking for is to increase the actual slider bar to approx. the same height as the thumbs themselves to give it more of a sliding progress bar look. Also maybe customize the sliders themselves a little bit. Is this possible somehow using WPF?

Hi I have issue whit theme changing in RadDock control. When I use StyleManager.SetTheme method for different controls everything works fine. But if I do this with StyleManager.SetTheme(myDock,new Windows7Theme()); then this method destroys the layout and disables the layout loading (to recover previous layout). App hangs and layout doesn't recover correctly. I need to implement the dynamic themes changing but RadDock doesn't seem to work fine.
