UI for WinForms forum missing & version 2016.1.112 not available in Control Panel

Two things quickly.

Why has the forum link to UI for WinForms (http://www.telerik.com/forums/winforms) disappeared from the main Telerik Developer Forums page (http://www.telerik.com/forums) and why is it no longer accessible directly but this sub forum is available?

Also, UI for WinForms Q1 2016 (version 2016.1.112) has been released but it isn't yet available for download and installation in the Control Panel. I've been waiting for some fixes for a while now and really need this latest version to able to continue with the build and release of the next versions of my applications.

I assume things will be up and running soon but wanted to post this in case these haven't been picked up on yet.

[Solved] Change color in a DropDownButtonElement-DropDownMenu for the vertical line

Hi all,

is there a possibility to erase (or set it to color white) the small vertical line (see attached pictures) in a DropDownButtonElement-DropDownMenu?
Or is it the radMenuSeparatorItem?

FillPrimitive fp = burgermenu.DropDownButtonElement.FindDescendant<FillPrimitive>();
fp.ForeColor = Color.White;
fp.BackColor = Color.White;
fp.GradientStyle = Telerik.WinControls.GradientStyles.Solid;

didn't work.

Kind regards
Oliver

Shortcut behaviour incorrect

First as a prologue, I am aware of the deficiency that radmenus do not show the accelerator key all the time, despite the windows default having been set. To get around that, I have added code which I have found elsewhere in this forum, basically this:

Public Sub ShowMenuShortCuts(ByVal AMenuItems As Telerik.WinControls.RadItemOwnerCollection)

Dim i As Int32 = 0

While (i < AMenuItems.Count)

Try

CType

(AMenuItems(i).Children(2).Children(0).Children(1).Children(0), Telerik.WinControls.Primitives.TextPrimitive).ShowKeyboardCues =

True

AddHandler CType

(AMenuItems(i).Children(2).Children(0).Children(1).Children(0), Telerik.WinControls.Primitives.TextPrimitive).PropertyChanged,

AddressOf MenuPropertyChanged

If (TypeOf AMenuItems(i) Is myMenuItem) AndAlso (CType(AMenuItems(i), myMenuItem).Items.Count > 0) Then

ShowMenuShortCuts(CType(AMenuItems(i), myMenuItem).Items)

End If

Catch

'Failure

End Try

i += 1

End While

End Sub

Public Sub MenuPropertyChanged(ByVal sender As Object, ByVal e As PropertyChangedEventArgs)

Dim tPrimitive As Telerik.WinControls.Primitives.TextPrimitive

tPrimitive = CType(sender, Telerik.WinControls.Primitives.TextPrimitive)

If (e.PropertyName = "ShowKeyboardCues" AndAlso (Not tPrimitive.ShowKeyboardCues)) Then

tPrimitive.ShowKeyboardCues = True

End If

End Sub

I am pointing this out because it may be relevant to current issue.

Ok let's say you have this in place:
- You have parent window, with a menu, where one of the items has an accelerator key of "a".
- You have a child window, with a control, with an accelerator key of "a"
So two controls with the same accelerator key. Here is what you do with normal windows forms to invoke one or the other
- If you HOLD DOWN the Alt key, and press your accelerator letter at the same time, this invokes the control on the child window.
- If you press and RELEASE the Alt key, the focus is now on the menu, and you can then type "a" to invoke the menu item.

But here is what happens if the menu is a radmenu:
- I press and HOLD DOWN the Alt key, and then press "a" at the same time. Result? Focus goes to the menu. It should not, it should set focus to the control on the child form.

Thanks for looking.

Incorrect CurrentRow selected after setting the DataSource in a sorted gridview

When the datasource is set for a gridview with sorting applied, the first row in the Rows collection is selected rather than the first row in the ChildRows collection. This causes the gridview to scroll to the position of the first row in the datasource rather than the first displayed row in the gridview.

Steps to reproduce:

Set the datasource for the gridview

Sort the gridview

Set the datasource for the gridview again

The first row in the datasource will be selected and scrolled to, rather than the first displayed row.

How-To Replace Row DataBoundObject with Derived Object?

I have a grid populated from a base class. The base class has a enum property to identify what type of derived object it is. When the user adds a new row and changes that enum value, I need to replace the object with the associated derived type. Example:

public enum ObjectType

{

Base,

ChildA,

ChildB

}

public class Base

{

public ObjectType Type { get; set; }

}

public class ChildA : Base { }

public class ChildB : Base { }

The grid will initially create a new row with a DataBoundObject of Type 'Base'.

When the the user changes the 'ObjectType' column to 'ObjectType.ChildA' I need to replace the row's DataBoundObject with a new instance of 'ChildA'.

The grid's DataSource is set to a BindingSource; who's DataSource is set to BindingList<Base>.

I tried to replace the object in the BindingList. Then set the BindingSource.DataSource to the updated BindingList. And then call BindingSource.ResetBindings(false) to updated the GridView. But I receive a NullReferenceException.

How can I replace the Row's DataBoundObject with a derived object?

Pie chart for ChartView

Hi Telerik team,

For the pie chart, I saw that Telerik tools that have smart labels(refer to the attachment with the red color box), there are few features like draw connecting line and labels border, sync labels border color and line color. But I can't find it in the property of visual studio for chartView, please advise. Is it need to write back end coding instead of using property to use those features?
Apart from that, the label(refer to left red color box of attachment) show in my pie chart is by percentage(%) but the label show in Telerik is in character for each categories, may I know how to set it?

Best regards,
Nicholas

[Solved] RadButtonElement Covers ContentImage

Hello,

When I add a RadButtonElement to my alert, it causes the ContentImage to be cut off at the top of the button element, despite the button being on the other side of the alert. See the attached images as an example.

Is there a BringToFront event (or something along those lines) for ContentImage?

Thanks!
