Hello,
I use RadGridView to display real data.
The grid contains objects and background thread modifies object propertis.
When I set filtering on gird and change object properties the filter seems not refreshing, and object is still visible even when it doesn't meet filter conditions.
I sow Real-Time update example and seems it works properly, but in example full object is replaced in data source, not only properies values like in my application.

Could You help me where is problem?

Hello,

I am altering the Edit Appointment Dialog and need to be able to keep the start time and end time in sync (e.g I increase the start time by 5 minutes and the end time automatically increases by 5 minutes...like Outlook does).  I was able to do the in the Silverlight version of the RadScheduler by using an AttachedBehavior, but this is not available in the RadScheduleView.  Is there a way to do this in the RadScheduleView?

Thank you,
Michelle

Am about to completely backout the upgrade of my Telerik controls from 2010 Q3 to 2011 Q1, way too many problems.

One of the problems is the eror below when clicking on a hyperlink I have in a CellTemplate in a grid.  I don't know if the problem is in the grid or the tab control since the grid is housed in a usercontrol which is shown in a tab control.  I'm having tons of issues with the tab control as well.

Is it possible for a programmatic update to the RadGridView.FilterDescriptors collection to be reflected in the column's FilteringControl?

E.g., this code doesn't get automatically reflected in the associated column's popup filter control.
  
But I'd like this code to update the FilteringControl thus providing the user with an alternative mechanism for filtering.

So is there a straightforward way to make that happen?

Many thanks!

We just got the WPF package last week, so it should be the latest release.

We've set up a basic GridView, but it doesn't allow us to sort the columns.

The XAML looks like this:

I've tried setting a SortMemberPath on the columns, but that doesn't buy me any ground. I looked over the GridView documentation on sorting, but I didn't notice anything out of place. 

My colleague set up the attached behavior at the bottom. I may have misheard him, but I believe he said he pulled it from these forums, posted from your team. Basically, we needed to know when the user double-clicked a row, and that does it for us. I tried removing it as well (just in case it was causing the problem), but it didn't change anything.

Thanks!

I downloaded the Q2 release and a quick test in WPF 3.5 works. I tried hosting the map in Winforms 3.5 and it fails:

I have a gridView that is part of a DataTemplate for a TabControl. One of my columns has a cell edit template that contains a textbox with a context menu. I need to bind the context menu to a collection on my viewmodel. but because it's not part of the virtual tree, I couldn't define the source in xaml. I managed to get it working by handling the Opened event and setting the DataContext of the contextmenu to the same as the user control. It all worked well, but then I ran into some trouble.

Elsewhere in code, I need to be able to call GridView.CommitEdit(), so I moved the DataTemplate code for the TabControl to a new user control to be able to call this method. Doing this however broke my code that sets the DataContext of the Context menu, because the DC of the new user control is not the view model...it is the entityObject to which its bound since it's a DataTemplate.

Is there anyway I can call the CommitEdit method from code-behind if the grid view is defined in a DataTemplate? Or possibly define the context menu elsewhere so that the datacontext can be set on it?

Hi,

I have a RadGridView inside RadPane and RadGridView has a context menu. If RadPane is in autohide state and I right click on RadGridView to open context menu, context menu is opened but RadPane gets collapsed and hence context menu also gets closed.

I will be very thankful if anyone can provide solution for this problem.

I have a variety of checkboxes in a grid where some of them will be bound to underlying objects (boolean) and others that aren't.  Those that aren't bound will not retain checkbox check marks, but they still allow them to be checked.  When clicking off such a cell, the checkbox will go back to being "unchecked".  I want to have control over these unbound checkboxes to make sure they're visibly "unavailable", whether that means preventing any checking activity at all or changing the appearance of the checkbox to a box with a red x or something of the sort just to let users know that the checkbox cannot and should not be used.

I tried hooking into various events such as CellLoaded, etc. but I couldn't find an event that would allow me to check whether or not the checkbox is checked to explicitly make a modification to an individual cell.  For example,  I tried the following which doesn't work:

void radGridView_CellLoaded(object sender, CellEventArgs e)

{

 

if (e.Cell.Content is DataFormCheckBoxField)

{

((

 

DataFormCheckBoxField)e.Cell.Content).IsEnabled = false;

((

 

DataFormCheckBoxField)e.Cell.Content).IsHitTestVisible = false;

((

 

DataFormCheckBoxField)e.Cell.Content).IsReadOnly = true;

}

}
