I have a grid that has a cell validating event, which sets the isValid property of the edit to false when required. As expected, I am unable to move away from the cell until I correct the error. However, I notice that the grid is still updating the underlying VM with the incorrect value. Surely this is wrong.
This is causing me an issue, because the user can still initiate a save (due to a complicated winform/wpf integration), and as such persist the incorrect value.
Hi,
The question is similar to pie chart. Basically, I have a bar chart, and the feature I wanted is that:
When mouse hover on bar, the according category axis label can be highlighted (customized color) too. Same goes that when mouse is over category axis label, the according bar area will be highlighted.
Same as selection behavior, I can click on category axis label to make a selection, drag-area to do multiple selection from category axis label, same as I do this from data plot area.
Thanks,

Hi,
I'm using RadDiagramView on big diagram and I need to export png images.
png encoding and 91 dpi is ok for my needs, so I'm calling ExportToImage method leaving default parameters as follows:
using (var stream = File.Open($"{filename}.png", FileMode.Create)){ radDiagram.ExportToImage(stream);}On big diagrams, i'm in trouble because the quality of exported images is very low (seems blurred); I cannot understand why.
I have cloned your github xaml sdk examples and pushed it on my personal account on this url https://gitlab.com/webartoli/repro-lowquality-exporttoimage-radtreeview. You can find a repro starting Diagram/Autoscrolling project.
Repro changes:
attached a picture with a comparison of the same shape on a small diagram (300 x 150px) and on a big diagram (6100 x 6100 px).
Am I doing something wrong ?
How can I manage properly all the options, in order to obtain the same quality regardless of the size of the diagram ?
Thanks

How to add insert to database functionality in RadDataForm
Trying out the property grid and haven't been able to figure out how I can override the default template for common .NET types such as float to use the RadNumericUpDown rather than a TextBox. I looked at setting a custom DataTemplateSelector as described here: http://docs.telerik.com/devtools/wpf/controls/radpropertygrid/features/datatemplateselector.html but this can only work if I know the property name. So my question is the following: how can I change the default float editor template in the property grid? I want to do this for integers, colors, and many more common types. I don't want to have to add custom attributes to all the properties either.
Thanks!

Hi,
the ItemsLoaded event is called using an IEnumerable of the items that were loaded. If the underlying collection of the VirtualQueryableCollectionView is an IQueryable (e.g. a DB-Queryable) and I want to iterate over the loaded elements, another DB-Query is created. The expected behavior should be, that it is only enumerated once and the list is sent in the ItemsLoaded event.
Best regards,
Philipp
