Hi,

I'm a licenced user of the WPF controls and have found a few issues during development of an application.  Originally i thought these issues were down to my use of some custom columns and the behaviour i need, however, after many a fraught hour testing and re-testing i eventually loaded the WPF Demo (Q2 2010 SP1) and looked at the sample.  To my amazment the samples also show the same behaviour!!

Issue 1: The first issue is is to do with editing cells and the scroll bar:
1) Start the GridView Editing sample from the demo's
2) Double click any cell to get the edit box
3) CLICK in the scroll bar on the right somewhere BELOW the handle (don't pick up the handle/bar and drag it as this works fine, it's only when clicking the free area either side of the handle).
4) In the grid there will now be a white cell (it can be in any of the columns not nessesarily the original column, this is more obvious when there is a horizontal scroll-bar)

I have tried many things (including cancelling the edit on scroll, which doesn't work as the event is only fired when the scroll bar is dragged!).  I can't turn virtualization off due to memory and performance constraints (though neither seemed to actually fix the issue). 

Issue 2: The second issue is with the filter drop down window when the grid is in defered scrolling mode:
1) Create a standard grid on a form, ensure the filters are enabled and there is enough data to generate a sizable vertical scroll bar (i.e data height is at least twice that of the visible area).
2)  Start the application with the ScrollMode set to "RealTime" (or the default mode).
    a) Open a filter drop-down for any column that has lots of unique values in it (this is to ensure the filter drop-down has a vertical scroll bar in the list)
    b) Scroll the filter list up and down by dragging the handle.  This should work as expected.
    c) Stop the application
3) Change the grid ScrollMode to "deferred" and restart the application
    a) Open the filter drop-down for the same column as last time
    b) Scroll the filter list up and down by dragging the handle.  This now doesn't move the scroll bar in the filter drop-down but DOES scroll the parent grid up and down!!

This is a very strange one.  The up and down arrows at the top and bottom of the scroll bar work as expected (as well as the mouse wheel) however the grab-handle scrolls the parent grid?!

I've been unable to find a work-around for either of these issues (and Google has not been kind either!!).  If nessesary i will open a support ticket but all the nessesary steps for replication are above.

I'm using the 2010 Q2 SP1 WPF Controls in Visual Studio 2008 in a standard WPF Application project.  Both of these issues can be replicated easily using either the telerik demo's or a new blank project.

Has anyone had this issue before and can someone please help (my client isn't a happy bunny!!).

Cheers

Hi!

I have a RadGridView bound to an ObservableCollection<MyObjectType>.

In one of my method I receive a "MyObjectType" object, and I've to select it in the RadGridView.

It was working without any problem, but it seems that the SetIsSelected mehtod is now protected and I can't access it anymore.

How do I do now? I receive a MyObjectType and not a RadGridViewItem.

Why this regression?

I'm very disappointed on this change.

I want my textbox or text area to support HTML types. Is it possible for any controls in WPF or telerik ( like text area or text block ) to support HTML type so that I can put  hyperlinks inside it.

 I require to have n X n grids (major grid-lines on both the axes) on my chartarea for whatever the range the chart is currently having. Please let me know how to do that.  I want something like saying AutoRange = true and be able to set the step ...

Hi,

I'm pretty new in WPF and Telerik RadScheduleView.

When I try to get RadScheduleView XAML for customization in Expressiion Blend via  Edit Template -> Edit Copy command I get a error

"Child with name 'HeaderColumn' not found in VisualTree"

It seems the issue is here


The same error appears at run-time when I try to set template to a control.

Thanks,
Anatoly

Hello,

In the DayViewDefinition I'd like to add a layer that contains a single line starting from the ruler that follows the current time.
How would I add such a layer?

Thanks

Hi,

I have created one RadGridView and I am looking for the functionality for floating help control. Whenever a user rolls over the mouse in the column header of a Radgridview this floating help control will popup with some pre-defined description about that header. As soon as mouse pointer is no more in the header, this floating control will disappear. Any other suggestions to implement this are most welcome. I am using WPF for my application.

Thanks,
Mark

I'm so trying to understand why there is 2 setup types of WPF 35 and 40?
I installed 35 and now while i try to install 40 it says its installed.

Can you mention the differences and what to install?

Hi,

We are looking at your calculated columns to allow users to define a custom calculation on a grid. ie " x column * Y column + 45 " where a user cna change any part of the calculation.

Is there an editor supplied to allow a user to change the calculation implemented? Your WPF grid control is much better than the competitions but we really need the "unbound expression editor" functionality you see elsewhere.

Can you help point us at a solution you provide for this at all?
