I have set the RadDock padding to (0,0,0,0) on one of my windorms, but every time I build the project, the padding gets reset to the default size (5,5,5,5).
This is the first time I've encountered this problem, I've done this on numerous other forms in the past few days without any issues. Any ideas on what could be causing this?
I've found out that there is a property called 'RootElement' which also controls the RadDock padding. The issue was resolved when I've set its sub property 'Padding' to (0,0,0,0).

I have a radgridview with a GridViewToggleRowDetailsColumn and I can set the visibility of the GridViewToggleButton the way I want through the RowLoaded event for each row. It was working fine until I need to scroll horizontally. When the GridViewToggleRowDetailsColumn get out of the screen and I scroll back to it, the GridViewToggleButton are now all visible.
I tried to find any event triggered by this without success. Even the IsVisibleChanged event attached to the GridViewToggleButton seems to be triggered only on the visible one.
Does anyone faced the same issue or have any idea of what could produce this behavior ?
Edit: Found the answer. It was a virtualization issue. Adding EnableColumnVirtualization="False" in the gridview properties solved it.
https://docs.telerik.com/devtools/wpf/controls/radgridview/features/ui-virtualization
After a few minutes of research, it appears that telerik WPF GridView uses virtualization to improve performace. This means that the state of what is in the screen is retained and as things leave your viewing area they are destroyed. This frees up memory space significantly, however can have some side effects as you are experiencing.
You can set EnableColumnVirtualization=false however Telerik has provided a help article that will likely answer your question more directly while not sacrificing the performance provided by the virtualizations. A link is below and following through the steps, it looks fairly straightforward.
https://docs.telerik.com/devtools/wpf/controls/radgridview/style-selectors/cell-style-selector
The recommended approach for customizing this behavior, and not turning off the virtualization, is to use a custom column. Try inheriting from GridViewToggleRowDetailsColumn and override CreateCellElement. It is the callback for creating the visual element in the cell, which is called, more or less, at the same time as RowLoaded. Then return null for those rows that you don't want to have a button for.
We had an issue that some targets in the end of the table couldn't be dragged even if they're set as draggable objects by using Ext.js 6.2.
After check we found that if we increased the height of the table window, some targets became draggable; If decreased the height, then more targets couldn't be dragged;
Is there some attributes to solve this problem? We guess dividing several pages might fix this issue, but we would rather show them in one pages..
The code isn't convenient to show, but we use Ext.dd.DragSource and Ext.dd.DropTarget classes to create the drag target and drog zone. And other codes I think is correct;
Thanks for your help:)
I am trying to save an WPF UI to an XPS file stream.
Everything works as it should but there is one problem with Grid that use Grid.IsSharedSizeScope. Although when WPF UI rendered the column sizing is honored it is ignored when the UI saved to XPS so there is no equal column sizing.
Does anybody know why this could be happening and if there is a workaround ?
I wrote an application that generates various printed reports, which involves programmatically creating XAML controls and adding them to a FlowDocument. I remember hitting an issue where "Auto" widths are ignored, so had to use numeric or "star" values. Rendering the exact same XAML "to screen" worked fine.
Perhaps your shared size scope problem is related to the same problem. I remember reading about this "known issue" way back when I wrote this stuff, but don't have a link sorry.
I've just looked at my reporting code and didn't find anywhere that I've used shared size scopes (which is odd given their tabular nature), so perhaps I hit the same issue at the time.
I have a Silverlight 5 app with a PivotViewer in it. This is binding with the data source correctly, but I need to force a rebind on the templates without replacing the data source and re-setting the entire control. The results are.... interesting.
We are using a ValueConverter to determine what color a tile should be, and this value converter can be adjusted depending on an external selection. At this point the INotifyPropertyChange of all the records are fired and a rebind occurs, but only on the currently visible template. This leads to tiles changing colors when zooming in and out as the other views have no been refreshed.
Can anyone tell me if it is possible to implement this in such a way that it would affect all levels of zoom? And is it possible to trigger a rebind without firing the INotifyPropertyChange?
Thanks
After considerable investigation, I came across this issue in the microsoft bug tracker:
http://connect.microsoft.com/VisualStudio/feedback/details/768779/silverlight-forum-issue-with-changing-items-background-color-for-sl5-pivotviewer
The description:
Create a simple data class that implements INotifyPropertyChanged, change all the items' color every 5 secs, but some items have different background color with different zoom levels. This issue was reported from Silverlight forum: http://forums.silverlight.net/p/262082/654612.aspx/1?Re+PivotViewer+SL5+Dynamic+Collection+to+change+item+background+color
So I guess that explains what the problem was. Just waiting for a fix now.
Okay,...I've recently inherited a downright shocking Silverlight 4 application and the Xaml is worse than you could possibly imagine. I'm going through a clean up operation and I'm looking to save time if I can.
One of my problems is that I've got a bajillion Button controls; some have a Style set and some don't. I need a quick and easy way (if one exists) to remove all of the Style attributes from any Button (or whatever) that has one set. Is this possible?
I have access to VS2010, KaXaml, XamlPad and Blend 4.
Thanks in advance..
Forgot about this question so in response to Robert Claypool's question,...No, not really.
What I actually did was remove all the styles and go through the big daunting errors list one by one. I tried a little find and replace magic first but that failed miserably no matter how clever my Regex got.
No choice here but to just hand-ball it I'm afraid.
