In my application, I'm able to bind a TreeView to a Well object in my application through object-relational binding as such:

this.wellTreeView = new RadTreeView();
BindingList<Well> wells = new BindingList<Well>() { well };

this.wellTreeView.DataSource = wells;
this.wellTreeView.DisplayMember = "name\\name\\name";
this.wellTreeView.ChildMember = "wells\\layers\\items";

This works and I am able to view the TreeView hierarchy and select the nodes in the form. However, when trying to get the nodes in code, the wellTreeView is empty (0 nodes) and throws an Index out of range error in:

RadTreeNode node = wellTreeView.Nodes[0];

My Well class is defined like so:

public class Well
{
    public string name {get; set;}
    public List<Layer> layers {get; set;}
}

public class Layer
{
    public string name {get; set;};
    public List<Item> items {get; set;}
}

public class Item
{
    public string name {get; set;};
    public decimal length {get; set;}
}

I don't understand why the wellTreeView is empty without any nodes despite being able to view the tree in the form. Surely the well is bound to the TreeView?

Hey there!

I wanted to ask if there's a way to visualise, the data from a specific RadGanttView, in a Timeline like the this:

Thank you.

Hey there!

I wanted to ask if there's a way to change the resource height to a fixed value... When i have a low amount of resources it works fine

But when I have a high amount of resources, the object becomes unusable:

I need to be able to define a fixed size for each resource, and if I do that with code I'm using in the first resource  ('SetResourceSize') then every single one of them will have the same small height (accordingly with the monitor of the user).

Is there a way to do that? Maybe by forcing a vertical scroll (something that i tried but didn't managed to do it)?

HI.

I trying to create a Connection in RadDiagram  With VB.net

My use case is adding a handler to detect mouse right click on the connection. Although the following code does not give an error, it does not work either.

Blow is my simple test code.

Imports Telerik.WinControls
Imports Telerik.WinControls.UI

Public Class RadForm1

    Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim con As New RadDiagramConnection
        con.Name = "Telerik_Connection"
        con.StartPoint = New Point(10, 10)
        con.EndPoint = New Point(100, 100)
        con.StrokeThickness = 5
        con.BackColor = Color.Blue
        AddHandler con.MouseClick, AddressOf Con_click

    End Sub

    Private Sub Con_click(ByVal sender As Object, ByVal e As MouseEventArgs)
        If e.Button = MouseButtons.Right Then
            Me.Text = sender.name
        End If
    End Sub
End Class

We’re long time Telerik subscribers. I love telerik but but i dread seeing ‘that’ notice that theres a new upgrade to the control set as i know i’ll be fiddling about with source to get things to compile. Winforms. 

Firstly, licx files arent updated with the version number of the new control set. Its a bit concerning, but at least i can do a [search/replace in files ] on old to new version number to fix this quickly.

secondly, when adding to the list of references, which file path should we be searching for an assembly? My solution has many projects and ive found several file paths. Some to the Telerik install directory (eg c:\program files(86)….), one or two from my user\username 🤯many from the lib\telerik directory beneath the solution\project directory.

i think ive finally realised that the update application works by switching out just those references from the old, to the new lib base file path for us. But id like confirmation please.

Hello!

I have two questions:

1) I'm trying (without success) to change the background color of my Application Menu (button?) Button on the left side of the Ribbon that opens (in my case) to the Backstage from inside Visual Style Builder.  Can you point me to the correct element please?

2) This one is a little more difficult to explain - I'll be attaching before/after images in case I'm not as clear as I'd like to be.

using RadRibbonForm there are Tabs.  Under the Tabs are Groups.  These groups contain buttons, lists, etc that live on the Ribbon.

I'm trying to set the background color for these groups and while I was successful in doing that, there's an unpleasant space/gap/padding? that surrounds the "group"

How do i remove that gap?  Also, how do i make this fill rectangular?  There should be no 'gradient' going from the background color - to white.

I can make the mods in-code if needed, the best choice would be to learn where to update these properties in Visual Style Builder.

Kindest regards,

Curtis.

Hi,

I have a grid within a panel and I want to adjust the panel height based on the total height of the grid.

Using this code:

Me.Panel1.Height = Me.grid.TableElement.RowHeight * Me.grid.RowCount + grid.TableElement.TableHeaderHeight + 5

It seems to work ok if I use "Fluent" theme but not for "VisualStudio2012Light". I have attached a sample form.

Any explanation for this and how do I fix it?
