How to ChartView.ExportToImage from List<ChartView>

Hi,

I have 3 ChartViews on a form, I wish to export each to a separate Image.

I would like my routine to be generic so I can reuse it for many Chart sets.

I am trying the following.

foreach (ChartView x in PnlCharts.Controls.OfType<ChartView>())

{

x.ExportToImage();

}

However the ExportToImage Method is not available. It only seems to be available if I directly reference the instance inserted into the form.

eg ChartView1.ExportToImage();

Am I missing something here?

Why can I export from the instance, but not from the same instance when it is contained within a list?

Dashboard design question

Hello, I'm new to C# and UI design. I have a broad question as I'm just starting out.

I'm creating a desktop app with Visual Studio. The dashboard will have multiple tabs, each loading a form where the user can enter different settings. What is the best way to save that info when the user is navigating back and forth between forms. The info is being entered into using comboboxes, textboxes and updown boxes. I've just started playing around and when I move from one tab to another and then return to the original form, the previously entered data/selections are cleared. I know I can do this by saving the selection to static variables and then reloading them each time the form is accessed. I also know that static variables are said to be avoided.

any info to point me in the right direction is appreciated.

thanks,

Rog

Automatic rearrangement of tiles and user resize of tiles

Hello! I'm new to the panorama and didn't dive into the code yet, so I might ask some foolish question - sorry in advance.

Question 1. I see in the panorama demo that if the user drags and drop the tiles, changing their order and position, the rest of the tiles are automatically rearranged. Is this done in the demo code, or is it a method of the panorama?

Is it possible to rearrange automatically the tiles after changing the size of on of the tiles? (I saw a thread where it was said that we have to do it manually, but it was in 2014, so maybe...)

Question 2. Is it possible for the user to resize the tiles with the mouse - drag from the right bottom corner for example? I guess if it is not an option of the control, there are still some other possibilities-we can check MouseOver, see if the position of the mouse is at the corner of a tile, change the cursor to indicate this<->, manage mouse click etc

Auto scroll Radtreeview when an item is dragged over

I am trying to drag a text item from a Radgridview and drop onto a Node of RadTreeView. I have a custom code that is executed when it is dropped onto the node. My problem is, my treeView has around 200 nodes. I want the treeview to scroll down automatically, when the mouse is moved over ( to the visible last node), with the dragged item. How do I achieve this? Any help will be greatly appreciated.

Thanks,

Ranjitha

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
