Question, I'm working on adding a version of "search as you type". However in this case there are numeric columns that are bound to this grid with aggregates on those columns.

So, what is happening right now, is upon binding the grid will populate and display its data just fine, but when I attempt to "search as you type", the overridden CreateFilterExpression() throws an FormatException was unhanded by user code "Input string was not in a correct format" error.

This is only happening when I bind a column of type double on the grid.....as I mentioned, there are aggregates on those columns, so I'd like to leave them as numeric types.

Any thoughts on a workaround or what I may be doing wrong? If you use the example from the demos section of your site and add a column of type double to the grid, I'm guessing you'll get the same error.

How would I go about implementing behavior similar to Windows Explorer, where if I have a node selected, then I left-click again on the node it will enter Edit mode? I don't want this to interfere with drag/drop behaviors, so the implementation should presumably handle the PreviewMouseUp event, perhaps? 

Hello,

Is there a way to stop the user to typing in a Date value but still allow them to select a date from the calender drop down, much like the EnableTyping property on the ASP.net version of the control?

Many Thanks

Hi Telerik Team!

I am studying your components ToolBar, DockManager other and would like to buy them in the future.

All very good and they work fine.

But there is a problem. I would like to implement a floating toolbar in my application, similar to the toolbar of the Expression Blend (for example).
Maybe you tell me the possible ways to solve this problem? It would be great to have this functionality for your components in the future.

Thank you,
Sergey

I've set the default and expanded images and the icons are showing correctly, but the black arrows still appear next to them. I thought the icons would override these arrows but apparantly they don't. How can I get rid of the black arrows?

Hi Telerik Team,

I upgraded from Q1 2012 to Q2 2012 using the Telerik Control Panel. The upgraded reported no errors. My project seems to be working fine. However, when I am trying to start the Demo application, I and getting a "Stop working" error. Prior to the update, the demo app used to work fine.

This is what I found in the machine's Event Log:

Application: WPF Demos.exe

According to this article, we can use different token in chartview to format our data.
I want to define a new token, for example a new token named such as #dateindays that
converts DateTime data to day number in current year. Is it possible to do so, and if yes, how?

Hi there,

I'm using WPF and Telerik's WPF controls for the first time and I'm trying to figure out how I can change the style of the button. Right now I'm using radio buttons to switch between different sections of an application, but they still look like regular buttons. I want to remove the background and have an icon appear above the text in the middle instead.
It should also have a specific hover and active state.

Thanks,
Jacques
