In this case, the control is populated with business objects. The AutoCompleteDisplayMember property of the control point to a property of this object. This property can have a similar value to more than one item from the source collection. When we try to select a specific item using the Text property, the control will select the first occurrence of the value that is found in the collection. This behavior can be improved to allow to select specific item from the collection with duplicate values.

When you inspect a RadGridView Cell with the inspect.exe tool you will see that the Value property is empty.

There is a MDI parent RadForm containing a RadMenu with items. There is a MDI child RadForm which also contains a RadMenu with items. The mnemonics are enabled for all the menu items. The menu merging is disabled (RadMenu.AllowMerge=false).

When you show the parent form together with the child form and focus the child form, pressing the Alt key highlights only the menu items from the parent form. It is not possible to activate the menu items from the child form.

Please refer to the attached sample project and gif file illustrating the obtained incorrect behavior and the observed behavior with a standard MS Form and MenuStrip

I would like to get the scrollbar style as it is in the posted image.

Windows Forms on .net 6.0 / 7.0 / 8.0 diverges more and more from .net Framework 4.x.

Hi

It would be cool if the SyntaxEditor automatically changed the default palette if the selected scheme was dark.

Hi,

Please, add a property  or method to the RadWebCam control to set video bit rate or quality. Currently is fixed a 4 mbits and it results in very poor image quality at high resolutions.

Please find attached images to see the difference  between snapshot and video recording. With fast moving pictures is even worse.

Thanks.

 

Add option to enter new value that is independent from the data source or items.

Add axis titles to the charts

Editable chart in RadSpreadsheet

Implement the export of notes (footnote, endnote) in the RtfFormatProvider of the RadRichTextEditor.

It would be nice if the grid column chooser would support grouping of columns similar to the jquery grid

I know that there is a RadRange Attribute but using it creates a dependency on Telerik.

Consider the scenario that the object to be configured via RadPropertyGrid is defined in a library that is used by multiple projects.

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

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. 

When the user clicks an already selected row while pressing the Ctrl key, the row should be removed from the current selection.
