Hi,

Is there a way to hide the Expand/Collapse button and the recover the space it takes? I would be replacing its functionality with code that expands and collapses the panel, i.e. no need for the button..

Thank you
Ali

MouseEnter MouseLeave events on Shapes in RadDiagram

Hi,

Am trying to do the simplest of things in winforms/vb using the RadDiagram ..

My use case is simply changing the color of a shape when the mouse enters it and back again when it leaves it.

I have been experimenting with the events and their behaviors and cannot explain/figure out the following :

- mouse leave event fires correctly on the boundary of the shape (works as expected)

- mouse enter event fires only when the shape is selected and when touching the connector borders (the four default ones - up/down/left/right). the mouse changes to resize cursor when touching the four corner connectors

Below is my simple test code -

Imports System.Globalization

Imports System.Math

Imports System.Drawing.Drawing2D

Imports System.Drawing.Color

Imports Telerik.Windows

Imports Telerik.Windows.Diagrams.Core

Imports Telerik.WinControls.UI

Imports Telerik.WinControls.UI.Diagrams

Public Class RadForm1

Public Sub New()

' This call is required by the designer.

InitializeComponent()

' Add any initialization after the InitializeComponent() call.

End Sub

Private Sub NewItemToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles NewItemToolStripMenuItem.Click

Dim shape As LayoutShape = New LayoutShape()

RadDiagram1.AddShape(shape)

End Sub

Private Sub RadDiagram1_ShapeClicked(sender As Object, e As ShapeRoutedEventArgs) Handles RadDiagram1.ShapeClicked

Dim shape As LayoutShape = TryCast(e.Shape, LayoutShape)

If (shape IsNot Nothing) Then

shape.BackColor = Green ' reset

End If

End Sub

End Class

Public Class LayoutShape

Inherits RadDiagramShape

Public Sub New()

IsEditable = False

Shape = New Telerik.WinControls.RoundRectShape(5)

AutoSize = False

BorderBrush = New System.Drawing.SolidBrush(System.Drawing.Color.Red)

ShouldHandleMouseInput = True

SetBounds(0, 0, 100, 25)

BackColor = Green

Position = New Point(100, 100)

IsEditable = False

AutoToolTip = False

NotifyParentOnMouseInput = True

End Sub

Public Sub LayoutShape_MouseLeave(sender As Object, e As EventArgs) Handles Me.MouseLeave

Dim shape As LayoutShape = TryCast(sender, LayoutShape)

shape.BackColor = Blue

End Sub

Private Sub LayoutShape_MouseEnter(sender As Object, e As EventArgs) Handles Me.MouseEnter

Dim shape As LayoutShape = TryCast(sender, LayoutShape)

shape.BackColor = Yellow

End Sub

End Class

[Solved] Button height with row details

Hi,

I have a GridView with Row details as from https://www.telerik.com/support/code-library/row-details-grid-for-q3-extended

Is it possible to make button of GridViewCommandColumn with height of row+details? See attachment.

I have tried to add new RadButtonElement in CellFormatting event, but still it has height of the row...

If no - perhaps it is possible to add button to row details? Idea is to make bigger button

Thanks

[Solved] How to detect Cancelation in custom Editor

Hello,

I have a custom Editor derived from BaseInputEditor based on a RadButtonTextBoxElement.

In the "EndEdit()" function I change another property of the selected object, how can I see if the user canceled the edit by pressing ESC, so I can prevent the change of the other property?

[Solved] Syntax Highlighting Strings (Custom Language)

Hello, I am in the process of settings up a custom Language Tagger for Lua. Following the example provided in the documentation (https://docs.telerik.com/devtools/winforms/controls/syntax-editor/features/taggers/custom-language). Everything seems to be working correctly, however I am having a slight problem with setting a String Literal. A numerical Literal example is provided by overriding the TryGetClassificationType function, however in attempting to do a similar approach for Strings does not give the correct result.

The " characters are colored correctly but the words between the " " characters remain uncolored.

Here is my TryGetClassificationType function (Note I am using Telerik Winforms in C++ but the C# code is very similar) :

01.bool TryGetClassificationType(String^ word, ClassificationType^ %classificationType) override {

02. int number;

03. if (int::TryParse(word, number)) {

04. classificationType = ClassificationTypes::NumberLiteral;

05. return true;

06. }

07.

08. if (word->Contains("\"")) {

09. classificationType = ClassificationTypes::StringLiteral;

10. return true;

11. }

12.

13. if (word->Contains("\'")) {

14. classificationType = ClassificationTypes::StringLiteral;

15. return true;

16. }

17.

18. return WordTaggerBase::TryGetClassificationType(word, classificationType);

19.};

And my tagger registration as follows:

01.RadSyntaxEditor^ newEditor = gcnew RadSyntaxEditor();

02.//Register the Syntax Highlighting Taggers

03.LuaTagger^ luaTagger = gcnew LuaTagger(newEditor->SyntaxEditorElement);

04.newEditor->TaggersRegistry->RegisterTagger(luaTagger);

05.//Set the Syntax Colors

06.

newEditor->TextFormatDefinitions->AddLast(ClassificationTypes::Keyword, gcnew Telerik::WinForms::Controls::SyntaxEditor::UI::TextFormatDefinition(gcnew SolidBrush(Color::FromArgb(255, 216, 160, 223))));

// Keywords

07.

newEditor->TextFormatDefinitions->AddLast(ClassificationTypes::Comment, gcnew Telerik::WinForms::Controls::SyntaxEditor::UI::TextFormatDefinition(gcnew SolidBrush(Color::FromArgb(255, 87, 166, 74))));

// Comments

08.

newEditor->TextFormatDefinitions->AddLast(ClassificationTypes::NumberLiteral, gcnew Telerik::WinForms::Controls::SyntaxEditor::UI::TextFormatDefinition(gcnew SolidBrush(Color::FromArgb(255, 181, 206, 168))));

//Numbers

09.

newEditor->TextFormatDefinitions->AddLast(ClassificationTypes::StringLiteral, gcnew Telerik::WinForms::Controls::SyntaxEditor::UI::TextFormatDefinition(gcnew SolidBrush(Color::FromArgb(255, 214, 157, 133))));

// String

10.

newEditor->TextFormatDefinitions->AddLast(ClassificationTypes::Operator, gcnew Telerik::WinForms::Controls::SyntaxEditor::UI::TextFormatDefinition(gcnew SolidBrush(Color::FromArgb(255, 180, 180 ,180))));

// Operators

11.

newEditor->TextFormatDefinitions->AddLast(LuaTagger::ObjectsClassificationType, gcnew Telerik::WinForms::Controls::SyntaxEditor::UI::TextFormatDefinition(gcnew SolidBrush(Color::FromArgb(255, 78, 201, 176))));

// Objects

This yields the following result: https://gyazo.com/6331b12a57135c478bd3dccf66037fe8

As you can see, the " symbols are being correctly colored but the text in between is not. How would I get the text inbetween the two " " to be registered as a String Literal?

Thanks!
