Using a RadForm and rad controls like the RadTextbox and RadDropdown, I create this form. It looks like this:

I save and close the form. I reopen and it changes all the formatting. It now looks like this:

Notice, that the spacing has been increased and the dropdown lengths have been increased. I'm pretty sure there's other changes too.

What am I doing wrong?

 

Thanks,

Scott

I would like to have a generic validation-mechanism, implemented in all controls. Hear me out:

A class ValidationInformation for containing all sort of validation information for a certain field, property, cell, etc. which has properties likes:

  • Type DataType
  • object MinValue
  • object MaxValue
  • int? MinLength
  • int? MaxLength
  • bool IsRequired
  • RegEx Mask
  • etc.

It also has a virtual method like bool Validate(object entity, object value, out string validationError).

A base class ValidationInformationProvider for retrieving validation information from various sources. It has some abstract methods for retrieval, storing/caching information per cell/field/property.

This base class has the following subclasses:

  • ValidationInformationProviderFromDataTable
  • ValidationInformationProviderFromAnnotations
  • ValidationInformationProviderFromXXX

Each provider is responsible for reading validation information from the source (DataTable, annotations on a property, etc.) and fill a ValidationInformation object.

Now the fun begins...

Each Telerik class, like RadGridView and/or subcomponents should get a method or event to retrieve ValidationInformation. When the event is not handled or the method returns null, the default behavior kicks in.

When ValidationInformation is provided, default behavior is overridden. Properties of editors van be set with values from ValidationInformation (like Minimum and Maximum of a GridViewDecimalColumnPlus or RadSpinEditorElement). At the end if editing the method ValidationInformation.Validate is called to validate the new value. The validation error can be used for popups, or tooltips, or an exception. 

This way a user does not have to think where to set which property of any Telerik control for any validation. This way a RadPropertyGrid and RadGridView can work the same way when it comes to data validation, regardless of all editors which work in the background.

We are trying to display read only versions of documents. Some of these documents are of type .docm and have elements like dropdowns and text boxes. Most of the documents are being converted properly but all text within these .docm elements are missing. We have tried loading into the RadRichTextBox control and directly exporting to plain text with no luck. We do not need full support for these elements but in order to use Telerik's library for our document viewer we need to be able to at least extract text from these elements.

Is this currently unsupported or is there some other provider I should be using?

Hi
I'm building a .net app with VB 2019.

With RadChartView, for some unknown reason, I can't change the Font on the Legend
Nor can I set the exact legend position when using following code

With myRadChartView

.ShowLegend = True
                    .ChartElement.LegendElement.Font = New Font("Arial", 12.0F, FontStyle.Regular)
                    .ChartElement.LegendPosition = LegendPosition.Float
                    .ChartElement.LegendOffset = New Point(1600, 300)

end with

NB: This was not working with previous release either.

Dear Sir,

I’m a retired computer analyst and program for my own enjoyment.

I recently downloaded your UI for Winforms product and played with your Image editor control.

A very nice control indeed. It does some great manipulations of images.

It would be even more flexible if a user were able to add their controls to the radImageEditor control, have access to the loaded image, and be able to add further options to be able to edit images.

Just a thought.

Kind regards

Phil Sargeant

To reproduce:

  • create a new project with Telerik RadForm, HighDPI
  • add material theme, activate the theme
  • add RadWizard, activate the theme
  • change the wizard to Aero mode

In the preview the PageTitle of the wizard page is visible. Run the project and the PageTitle isn't visible anymore. The color of the PageTitle background is also not correct. I think there is a problem with the resources.

When using the new Office 2019 Light theme in the SyntaxEditor there are no scrollbars displayed in the CompletionList window. Also the list is not scrollable using the scrollwheel. Only when using the arrows on the keyboard.

When using the fluent theme it is working fine.

See attached screenshots.

It used to default to the control default and now it defaults to a theme. 

It seems to also not recognize controls I add to the forms until I do a build. I shouldn't have to add that step before I select debug. 

Acting very, very strangely.
