Hello dear Telerik Forum.

I have a memory leak problem, where opening views add up in memory, because they are still somehow referenced and thus not GCed.

I've implemented Prism and Telerik both in my application. I've also implemented the ScopedRegionNavigationContentLoader,  the RegionManagerAwareBehavior (and everything else required to open views in new tabs) from Brian (Prism) and the RadTabbedWindow in my MainWindow. So when I execute RequestNavigate from the MainWindow I open new Tabs.

Following happens:

When I execute RequestNavigate commands from the MainWindow I successfully open a new tab which then builds the view, existing of multiple subviews. This works correct so far.

Now when I close the RadTabItems the Views still stay in the memory. It seems there are still references in the RegionManager about the once spawned Regions/Views. Those add up when using the application over hours.

So my question is:

How do I unload the Region/View in the RegionManager of the MainWindow when I close the tabs?

I'm looking for a clean and global solution, where I dont have to implement code in every class.

Extra information:

- There is one RegionManager in the MainWindow, which manages all Tabs and so.

- Each Subview gets its own new RegionManager instance.

How to disable or overwrite background brush for selection in the TreeView?

What kind of templates I will be need to rewrite? Cause there's template for RadTreeViewItem  but I cannot reach this brush.

Hello,

I am having an issue with RadMultiColumnComboBox. I am having to set to a large width for them to not line wrap. When I select an item it is doing this:

How can I prevent it from doing this? The width is more than twice the size of the largest element, and it is set to single select so there is no reason to wrap the text.

I want to change the background of a merged cell based on the value of another column in the same row. In the SelectStyle method in class MergedCellStyleSelector which inherits from StyleSelector, I can only get the cell value but cannot get the bound entire data item, is there anyway I can get the bound row data item?

Hey,

as in the title the event doesnt trigger. It does work with the Widget "WidgetContentType = TwoStatesContent".

Im using a custom form for testing: https://pdfhost.io/v/xQU.fKEP6_24_anlage01_bauantrag_2021https://pdfhost.io/edit?doc=5b66dfdd-fafc-4589-bad0-c1608a8ecf1c

Hello Everyone,

I am currently Testing if we can switch from Word to Telerik RadRichTextbox. For that i want to be able to get notifications/events when a User Clicks on a Checkbox. I know there is the DocumentContentChanged event but that fires always and i dont think that ist viable for a document with many Checkboxes.

Is there some Event that would tell me which Control was changed?

Hi,

I have a RadGridView, and have added a ColumnGroupDescriptor to `RadGridView.GroupDescriptors`. I have also added an AggregateFunction to `GridViewColumn.AggregateFunctions` for several columns.

The aggregateFunction results are displayed in the grid's footer, each group's footer, and each group's header.

I now want to add an aggregateFunction that, only in the group's header, shows how many rows are in the group. I do not want this result to be shown in any footers.

I understand that this second point could be achieved if I had used GroupDescriptor instead of ColumnGroupDescriptor, however I do still want to be able to add other aggregateFunctions to columns and have these results show in both headers and footers.

I have currently attempted this by adding a small prefix to the AggregateFunction's "FunctionName", indicating it should only be shown in group headers; and then modified the GridView template to filter AggregateFunctions by this prefix as needed for headers and footers. However, this is not an elegant solution, so I was wondering what you would recommend.

Thanks, Richard

Dear Support Team,

I am using the RadGridView in my application for view and data modification. I would like to add Combobox editor in particular cell based on condition in single column. I cannot find such solution in documentation.

If it is possible then How can i bind the item source to that particular Combobox editor? 

Kindly provide example so I can implement in my project.

Thanks & Regards,

Hiren Lad
