Hi,

i have a scenario where i would like to make the RadDocking always dockable. When you right click and get the options(Dockable, Floating, TabbedDocument, Auto Hide, Hide and so on) i would like to hide the Dockable item from the ContextMenu so you can't turn Dockable off.

Thanks.

Month Navigation of Mutliple Row RadCalendar

Hello everybody,

I have a Calendar extended over 3 rows. By clicking on the navigation buttons ("left" or "right") that calendar jumps over 2 months back or forth.
How can I make it move on to the next or last month instead?
If it's displaying the months Juny-July-August I want it to go to July-August-September for example.

Thank you very much!

RadGridVIew with 50 columns and 40 rows performance

Hi,

When I create a simple RadGridView (*) with 50 columns and 40 rows that are visible on the screen at the same time this becomes slow. Both the initial filling of the grid and scrolling through them is slow.

Is there some option I missed?

When I profile it almost all of the time is spent in Windows dll's:

Functions Doing Most Individual Work
Name Exclusive Samples %
[PresentationCore.ni.dll] 75,78

Functions Doing Most Individual Work
Name Exclusive Samples %
[PresentationFramework.ni.dll] 10,20

The system I ran the performance test on: Intel Core i7-3632QM 2.2Ghz, 8G memory.

(*)only text columns, no converters, no sorting, no filtering

Is dragging and dropping an image into the RichTextBox supported?

Is dragging and dropping an image into the RichTextBox supported? It doesn't work out-of-the-box and I've always tried the TelerikEditorDemo_WPF example without luck. Scenario: Dragging an image from the desktop and dropping it into the RichTextBox.

TemplateSelector refresh when object changes?

In my app, I have 4 data templates that represent the state of points on the chart. This all works fine when first drawn, and my TemplateSelector assigns the proper template to the point based on the state of the underlying object.

My problem is that when the underlying object changes, I need it to trigger a refresh of that point, to get the chart to re-evaluate the TemplateSelector to apply the correct DataTemplate to reflect the new state. Is there any way to set up a binding, or absent that a way to poke it from the code-behind in a way that's not terribly horrible and get it to re-plot a single point? The only way I've found is to re-plot the whole series, which is a big performance issue with large datasets (10-50k items).

Thanks,
Louis

RadMap Geo Fence Help

I'm busy evaluating the RadMap and controls which we will buy soon, at the moment I need help, can someone please help me get started with following.

I need to set-up a geo fence with one or many map markers that will alert, assert when the fence boundaries are crossed OR entered, so far I only am able to create shapes with markers and am unsure of how to progress with the fence boundary detection.

Thanks in advance.

ActiveX control in a RadWindow

Hi,

I've noticed hosting an ActiveX control in a (standalone) RadWindow doesn't work. Following the correct steps (as mentioned here), the ActiveX control isn't visible. I put this in a test-project and when I host it in a normal WPF Window, I can see the control. Is this a known problem?

The same goes for an ActiveX control on a HTML page hosted in a WebBrowser. The HTML page will show the ActiveX control correctly in a normal browser, and in a WebBrowser in a WPF Window. Change that WPF Window to a (standalone) RadWindow, and the ActiveX control will no longer be visible.

I mentioned "standalone" twice. What I mean is when you remove the StartupUri from App.xaml and add the following in App.xaml.cs:

var mainWindow = new MainWindow();

mainWindow.Show();

If you don't do this, you will see the RadWindow inside a WPF Window and the Active X control still works. But seeing a RadWindow inside a WPF Window is strange.

So how can I get an ActiveX control to be visible inside a RadWindow?

Thanks,
Peter

Get Height of Y-Axis

I am using the CartesianCustomLineAnnotation to set the VerticalTo property. I would like the vertical line to extend the entire height of the chart from 0 all the way to the top. Since I am generating the chart using data from a database query I can not know the scale of the y-axis. Sometimes it is 0-100, other times it can be in the millions. The chart does a good job of adjusting the Y-axis labels to display data to scale, but since I am hard-coding the LineAnnotation, sometimes the VerticalTo is lower than the actual height of the Y-axis.

Is there a simple way to set the height of the line annotation so it always goes to the top without hard-coding a really large number? The properties off of VerticalAxis do not seem to help.

Thanks in advance.
