Hi,

I am using aggregate function to calculate sum of a certain column in my grid. However, the sum value is displayed both on the footer as well as the group header. How can I hide the value for m showing on the group header?

Also, I am doing the grouping programmatically, is there a way to hide the column that is grouping member from the showing in the grid? Currently, the group column displays its value in the group header as well as in the grid itself. I think it is sufficient to have the data on the header only. How can I achieve that?

Regards

I have an application that uses RadDocking to host a RadGridView control.  When the application initially loads the grid's databinding, sorting, filtering, grouping, etc. work fine.  However, if the pane containing the RadGridView control is pinned, unpinned, or floated all user customizations to the grid such as sorting and filtering are lost.  It appears that the the grid is reinstantiated when the user performs any of these actions.  I have set IsContentPreserved to True in the RadPaneGroup that hosts the RadGridView, but the grid's state is still not preserved.  Is there a way to preserve state in this scenario?

 

 

 

Thanks for any suggestions.

Steve

 

I have tried the latest WPF4 build 01582RadControls_for_WPF40_2011_2_1010_TRIAL_hotfix.zip and RadControls_for_WPF40_2011_2_0920_Trial_hotfix.zip.  I have verified that the assemblies are in the proper place.  Had no problem with Telerik.Windows.Controls.RibbonView; however when I run my program I get the following exception when trying to render the MainWindow.

Could not load file or assembly 'Telerik.Windows.Controls.Docking, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies.

Anyone else having this problem?

Thanks in advance,
Steve

P.S. The Examples app doesn't run either.

Hi,

I have a typical tree list setup:

        <telerik:RadTreeListView ItemsSource="{Binding OuterList}">
            
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding MiddleList}">
                    <telerik:TreeListViewTableDefinition.ChildTableDefinitions>
                        <telerik:TreeListViewTableDefinition ItemsSource="{Binding InnerList}"/>
                    </telerik:TreeListViewTableDefinition.ChildTableDefinitions>
                </telerik:TreeListViewTableDefinition>
            </telerik:RadTreeListView.ChildTableDefinitions>

    </telerik:RadTreeListView>

Initially, OuterList, MiddleList and InnerList were all ObservableCollections. But when I'm adding or removing 100s of items from a list, ObservableCollection fires an event for each change and a huge amount of time (minutes) gets used up in RadTreeListView, apparently figuring out the new UI layout.

So I decided to make MiddleList a List<MyObject> property. I'd calculate the new contents of MiddleList elsewhere, then I'd set the MiddleList property to the new list. Changing that property would trigger an INotifyPropertyChanged.PropertyChanged event. All the changes would become visible to RadTreeListView in a single event.

Unfortunately, RadTreeListView doesn't seem to respond to a PropertyChanged event that changes the TreeListViewTableDefinition's ItemsSource. When I set MiddleList to a new value, the list of displayed items does not change.

Is there a way to force RadTreeListView to re-load its table definitions? Is there another approach I should be taking?

Thanks,

Hello,

I do understand what controls are supported and which ones are not.  We are at a point where we need to automate the testing of our application and unfortunately the controls we use most are the ones unsupported (ribbon, docking, tab).

I've read forum posts and got bits and pieces of when they will be supported.  My question is does Telerik have a roadmap as to when ALL of the controls will be fully supported?  Seems the WinForms support was added recently.  Although it may be a painstaking process for us developers, we may have to look at oter suites that do support automation.

Thanks,
Chris

Hi,

I have some RadTabItem and each one have a gridview which are binded to lists of type ObservableCollections.
Each line of gridviews have on it a GridViewCheckBoxColumn and a GridViewDataColumn  which show when the checkbox was updated for the last time.
The collections contains entities which implement INotifyPropertyChanged.

The issue come when I start the application, I switch to the third tab I check the checkbox on one line and the field of the line is updated.
I switch to another tab and switch back to the third tab, check the checkbox on one line but now the field of the line is not updated.

I thought at the beginning that it was a problem of the entity which not update the data at it should but the entity have always the right values.
I also added a combobox in one tab for testing and binded it to the same collection of the gridview and the combobox show always the correct updated values so the problem seems to come from the gridview.

Here is the gridview of one tab:

And here is the combobox which is binded correctly to the collection:

Did you already experienced this issue?
Thanks

I have a contextual tab, which I show using


This has the effect of displaying the tab and changing the current active tab, which is very annoying.  I was under the impression that this was against Microsoft's guidelines.  If you draw a rectangle in PowerPoint 2010 the Format tab appears, but the active tab remains on whatever you had selected.

Is there a way to simulate the same functionality?  I have tried IsVisible, but that seems to be just a getter.

Thanks

Hi,

I'm trying to get the Office 2010 look & feel so i'd like to apply glass effect on the RadRibbonWindow, wich works fine with a standard window (http://msdn.microsoft.com/en-us/library/ms748975.aspx).

Have you already set a handler that would prevent that feature to work ?

Regards.

Hey, I'm not sure if this is possible, but can a RadTreeView handle being inside a ScrollViewer and letting it be in control of the scrolling??

I seem to have lost 2 abilities that i did before,

1) the ability to scroll up with an item when dragging
2) the ability to use the scroll wheel when my mouse is over the TreeView

you can see what i mean in this screen capture, the first part shows the not being able to drag an item upto the top, and the second part shows the ability to use the scroll wheel when i mouse over the scrollbar but not the scroll wheel..

also note, i have totally customised the look and feel of the RadTreeViewItem's... but it is indeed a RadTreeView.

http://www.youtube.com/watch?v=iE1rbqdDlmA

The reason we need the scroll viewer to work now, instead of using the RadTreeView's control is because we have the small panel that is pinned to the bottom of it, but when there are only a few items it appears directly below them, rather than being constantly pinned to the bottom of the screen.. its almost a "Traveling" toolbar.

Any help with this issue would be appreciated.
