Repro steps:

1. Create a RadVirtualGrid
2. Give it a DateTime column
3. Make sure the editor (VirtualGridDateTimeEditor) accepts dutch formats for dates (dd-MM-yyyy)
4. Add a row with value: 30-11-2023
   
   
5. Double click on the value and try to change it my literally typing: "31-12-2023"
   

Observed behavior:

• A field with the value 01-12-2023
  
  (this happens as soon as you type "31")
• The user needs to first enter the month, then the day to correct this.

Expected behavior:

• A field with the value: 31-12-2023

Observation / suggestion:

• The controle tries to validate and correct EVERY input, even when the input is not finished yet. Everybody knows "31-11-2023" is an incorrect value. But during changing it, this should not matter. The scope at that point should be: Making the user happy by accepting the input. When the user leaves the field, or enters the last digit, validation should take place. Or, if halfway entering the value, the totale date is invalid, do not change it and wait for the user to complete.

Hi guys,

              It would be great to be able to set the day start/finish times in your Scheduler.

Your Scheduler control is fantastic, but I am building a Scheduler for a company that operates over 24hrs and the shift hours are

6am - 6pm

6pm - 6am

both shifts are classed as being the same day even though the nightshift crosses over to the next day.

 

I would like to be able to adjust the 24hr period that defines a day so that in month view the appointment will not carry over to the next shift.

and in day view, the schedule will start at 6am and go through to 6am.

If you could implement this, your scheduler control would be even more powerful and awesome.

Thanks!

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. 

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 Telerik Team!

Even though your components are one of my favourite 3rd party tools that I use in software development for years now; I have to rise a bug ticket for component called "TelerikMultiSelect". The problem is that when the autocomplete box's data source is updated for the first time using a timer's event the autocomplete box remains empty and I have to click outside and the inside of the input again.

Please consider investigating and fixing this issue.

 

Kind Regards,

Hi team,

 

To reproduce: Set RadLabel.AutoSize = True, RadLabel.MaximumSize = (100,0). When set the Text property to a string with width wider than 100, the text won't cut off (when TextWrap = false) or wrap to a new line (when TextWrap = true).

 

Workaround: Manually set RadLabel.LabelElement.MaxSize = New Size (100,0). The behavior of the control becomes normal. But it is not convenient as we have to set a large amount of label controls in the code behind rather than to set them in the designer.

 

Thank you.

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

How to create a PropertyGrid and initialize it like this,modify the 'segments' arraies as I modify the 'count'

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. 

Request a JSON tagger for the SyntaxEditor

Dear,

I wonder if it is possible to consult the release history by product & control & version, next to the (already existing) release history by product & version & control?

This feature has benifits:

• see how a given control evolves in time
• quickly find if a bug/feature has been implemented by control

This request can be applied for all your products.

Kind regards,

Peter
