I'm trying to set the visiblity of a RadMenuItem based on code. I've seen some other posts but they seem rather difficult or sloppy to maintain. My end goal is to run it through a function that will return true or false. I've simplified it for discussion purposes.

This code below should work. But it doesn't. Any ideas?

<telerik:RadMenuItem runat="server" NavigateUrl="~/users/manage_users.aspx" Text="Users" Visible='<%# "false" %>'>

</telerik:RadMenuItem>

I don't get an error but the menu item still shows.

Any ideas?

Thanks,
Rob

cant use RadRichTextBox .net 4 assembly in my .net 3.5 framework application

I have C# Winform Application running in Visual Studio 2008 and I use .net 3.5 framework. Now, I want to use RadRichTextBox control in one of my form.

The issue is I am not able to use RadRichTextBox control since it is based on .NET 4 framework and the target project is 3.5 framework.

Since our most of our customers using 3.5 .net framework we cant move our project to .net 4 framework. So, with this constraint, please let me know how to proceed with this.

Thanks,
Vinayaka

[Solved] Scheduler KeyDown and KeyPressed Event Issue

Hi,
Just reporting what I think might be a bug.
Using RadScheduler (2011 Q3) in any ViewType, the following events don't fire when pressing arrow keys:

KeyDown
KeyPressed
CellElementKeyDown
CellElementKeyPressed

Can you think of any workaround for this issue? I wanted to use it for solving this.

PS. I hope you don't mind me posting bugs all the time. I just like your product very much and this is the least I can do to help you improve them ^_^

[Solved] DateTime Column format when grouping

When dragging a DateTime Column with a format string to the group-by bar, the format string is ignored. This could both look bad, as well as group incorrectly.

For example I have a DateTime column where I only want to show the date, not the time. When grouping by this column it will show the time in the group header, and use the time values for the grouping as well.

Anyway to solve this?

[Solved] How do I just show the data (like RadSparkline)?

I would like to show data in WinForms in a fashion that's similar to the RadSparkline control for WPF.

I would like to hide everything from the chart except the actual data being shown.

I will also be updating the data in real-time, about every second with multiple charts on the same screen.

Does the WinForms RadChart have some way to hide all the extraneous information such as legend, axis, labels and to make the chart's data area fill the whole control?

Also, is RadChart up to the task in terms of performance for real-time data display or should I be using some other Telerik control for this?

Thank you,
