Hi!

I have a dataTable and one of its columns is a image (bitmap) column .
I've been trying to  show this images in my GridView by binding it to GridViewImageColumn but I don't get it. 

I read that GridViewImageColumn accepts byte[] and string types so I tryed to use this methods to convert the bitmaps and then put the result in other column and try to bind it to the  GridViewImageColumn: 






The column in my gridView is still empty.....

I've tryed this code:



And this:




I would really appreciate any help....

I'm looking for a command button in WPF, but it doesn't appear as if there is one.

I would like my command buttons' styling to match the other Telerik controls in the window. Would I be better off trying to match the style with the standard Visual Studio WPF command button or the Telerik WinForms Command Button?

Hello,
I am building an application that plots points taken from the USB COM port, into C#, then i want to display these data, it reads a sample every 4 ms, the Y-axis is the value read, and the X-axis is the time.
Can it be done using your Grid View/ Live data control ? 
And is there a better control that i am not baying attention to ?
Any help is appreciated, 

Thanks in advance.
Regards,
Nada.

I'm working on a project(appointment scheduler and clinic management system) for several months now using WPF Telerik controls and OpenAccess ORM.
But I have no idea how use RadScheduleView and OpenAccess ORM.
I really need an example which demonstrates how to use these two tools together.
Yana ,Kalin and  the other Telerik guys , please Help ..
Thanks in advance
hiwa

When I used Telerik WPF VS Extension to convert my project to Telerik WPF project there was a check box to 'Add referenced assemblies' to project.

When I checked that and chose the few assemblies I needed in my project, I discoverd that ALL the Telerik WPF assemblies have been copied to ...\lib\RCWPF\2013.2.611.40, not just the referenced assemblies as the check box stated. Also ALL the language assemblies were copied as well eventhough I do not intend to use localization.

When I build my solution now only the assemblies I referenced are copied to bin/Debug folders so why did the WPF VS Extenstion copy ALL the WPF assemblies to my solution and can I just waste my time tracking down assemblies I do not need and delete them?

Also, all the localization assemblies are copied to bin/Debug eventhoug I do not need them... why is that and how do I get rid of localization assemblies? Can I just delete them?

Are there plans to implement animations for the WPF TileList control as has been done with the AJAX TileList control? If this has already been implemented, I can't seem to find the documentation on it.

Hi  all,

I use GridView + DataPager with QueryableCollectionView , mainly do CURD operations, everything worked well but add new item.
Please note I assign IQueryable source to QueryableCollectionView for solving huge data performance issue.  When I call gridVIew's BeginInsert();  , one new row will be shown in first row of GridView.  That's fine, but there are some questions. 

1. The insert row will disappear if I click another row(With setting ActionOnLostFocus = ActionOnLostFocus.None),   I cannot find it in grid view any more. because I have added it to EF ObjectContext, so if I do this once and then SaveChanges() , the two entries will be inserted into database! 
I have used AddingNewDataItem Event , but I still can not find the new item in QueryableCollectionView and GridView.Items

 public void AddingNewDataItem(object sender, GridViewAddingNewEventArgs e)
        {
            var entity = copyItem ?? new TOrginal();
            copyItem = null;
            IntializeNewItem(entity);

            var model = new TModel { Model = entity };
            CurrentItem = model;
            e.NewObject = model;
           // AddModelToCollection(e, model);

            if (CheckItemIsNew(CurrentItem)) return;
            CommonManager.Add(entity);
        }

next..I also try to insert Item into QueryableCollectionView directly, the gridview even do not show new item..

So I only can do delete it from EF context when CurrentItem change...

2. How to make Insert Row always visible when Adding new Row and Click other rows of this grid.??? 

Can you please give me some hint? It driven me crazy.

If you cannot solve this, can you please give me one solution for big data and CURD mechanism. 

Hi there,

I followed this discussion and link to get the styled validation running and it's almost there, there's just one (well, maybe two) issue(s) I can't really put my finger on right now.

The style used is taken from the thread above, verbatim.

First is too 'eager' styling after INotifyDataErrorInfo completes (since I'm using INotifyDataErrorInfo to validate each row's view model - so effectively all cells - in the intercepted 'RowEditEnded' event) , here's a reference picture and here's one after row view model validation . failed. Notice how all rows are lit up? None of them have the sliding popup on the exclamation marker, nor the popup with error, so I bet it's an easy style fix, but right now I don't have the time to explore it on my own, so I'm asking at the source.

[EDIT]: Peculiar thing, it seems to happen only on the first validation, then it works as expected.

Other thing is this errors marker, since the validation returns a List<string>, how could I easily customize this template to either not show the pop-up at all or show the error list?

Hi !

We try to make an autocompletebox where some of the items could be disabled individually.

We first try to make a BoxesItemTemplate but the item’s “little cross” which delete the selected items from the list where not in there.

So we decided to make a Style/template for the complete “autocompletebox”.
In this style we define the item container style in order not to have the "little cross":

And we did a BoxesItemTemplate in which we put a button for the "little cross" that should delete the item when pressed. But then we were enabled to bind to the delete command (the command that delete the item).
On our button we try some things like :
But it does not work. I suppose we do not give the write arguments (perhaps the "item" as parametter)

Do you have any solution?

The complete style/template:

Hi All,

Thanks
