GridViewRow

 

grdRow = (GridViewRow)grdCell.ParentRow;

 

 

RadGridView

 

childGrid = grdRow.ChildrenOfType<RadGridView>().FirstOrDefault();


Please let me know

I currently have a Loop going through a cube which returns the name (Caption) of its items.
However as this is an OLAP cube I want to distinguish between user defined and attribute hierarchies. I thought the best way to do this would be to give each one a different color (so give User Defined Hierarchies a blue font and Attribute Hierarchies a red font for example).

I thought this would be simple but the method I tried below threw alot of errors, while other methods turned all of the items a particular colour rather than just the items I wanted.

Has anyone got an idea of how I could change an items colour depending on its value??


Window1.xaml.cs

I am using percentages in my graphs but the y-axis label as well as the item labels show 100% as 100.00% or 95% as 95.00%. Is there a way to make it show only whole numbers?

Thanks,

Well, my question is not related with the radwindow but I hope you guys can help :)

I have a windowless WPF application and I want it to be draggable by the users.

I can make it dragglabe by returning HTCAPTION in the WM_NCHITTEST message like this:


But then, the click event of the buttons inside the application doesn't work...

-----

When I add "DragMove" to the "MouseLeftButtonDown":


Then the problem is, if I click one of the buttons, I get an InvalidOperationException.

User interface :)

Does anyone have something in mind for this?

Good morning, afternoon, evening,

I am having trouble figuring out how I can center a RadWindow using WindowStartupLocation.CenterOwner when I open it from a non-wpf application.

I used the following code in my winform app to open a dialog that is a System.Windows.Window.  When I convert it to a RadWindow, it doesn't work and I am at a loss as to how to duplicate functionality.

 

 

 

var dlg = new MyDialog();

 

System.Windows.Interop.

 

WindowInteropHelper hwndHelper = new System.Windows.Interop.WindowInteropHelper(dlg);

 

hwndHelper.Owner =

 

new IntPtr(Globals.ThisAddIn.Application.Hwnd);

 

dlg.ShowDialog();

How can I center the window?

Please assist.

Thanks,
Alan

PS.  I have a support agreement but decided to post here so that others might benefit from response.

I have a the following column definition:  I want to be able to sort this column on the Sailor.Name property. How do I accomplish this?

Thanks in advance,

Hello!

I want to export from a RadGridView to Csv format. The ToCsv() method work fine, the only problem is that I get to much information since I have objects in my columns. And what is displayed to the user is controlled by the DisplayMemberPath or a CellTemplate.

So the question is, how can I filter the export so it only takes the displayed values? Do I have to loop through all the rows and if so how do I fetch the displayed value?

Best regards/
Anna

Hi.. I have the following. The autocomplete does not work unless the Combo dropdown is open. Any ideas why. How can get the autocomplete to work when the Combo has focus.. thanks again for your help.

Hi,

I am using the datafilter in the mvvm pattern, with the filter collection data stored in the viewmodel, which is then used to build a query to run against a WCF Data Services / OData IQueryable entity.  I'm not connecting the datafilter to another itemscontrol to be populated with ItemProperties, but rather creating my own item properties via reflection and linq off the entity type.

One issue is that I cannot bind to the FilterDescriptors property of the datafilter as it is readonly, so instead I am using a bit of code-behind code to persist this collection between the view and viewmodel when the datacontext changes.

The inability to bind to FilterDescriptors is causing one problem, which is why I am posting here.  I am saving/loading the filter data to/from a database, and would like to know when the data becomes 'dirty' (so that i can indicate visually that the data should be saved).  This is ok for filters being added or removed (via the CollectionChanged event) or for the logical operator being changed (via the PropertyChanged event), but I cannot find any way of detecting when the value of any of the simple filter properties (Member, Operator or MemberValue) have changed.

I've tried adding handlers for all sorts of events on the datafilter and on its viewmodel, but none of the handlers are hit when editing the filters.  I have even looped through the RadDataFilter.ViewModel.CompositeFilter.Filters collection, adding handlers for each item's PropertyChanged event, but still nothing.

So, is there something I can do that I have missed - or - can an event be added when these simple filter values are changed, or can the FilterDescriptors property on the control be made bindable?

Thanks.
