Hi,

I have sucessfully bounfd my collection the the grid.

After editing the contents in the Grid's Cell the application crashes, with a bizarre result: A File Dialog box pops open looking for :-
r:\WPF_Scrum\WPF_Team\Sources\Development\WPF\GridView\GridView\Cells\GridViewCell.cs.

What on earth!!!!


I cancel the box and and I get TargetInvocationException was unhandled exception

System.Reflection.TargetInvocationException was unhandled

Hi,

we (again after a stopped approach due to missing documentation) start a project using your WPF Controls.
We currently use (just for silverlight) another Linear gauge - and there we simply set Orientation="Horizontal".

We messed around a lot with your linear Gauge (documentation became much better) - but could not find out how to creat a horizontal gauge.

The other thing is about Radial Gauge.
We need a 180° Gauge - and had problems to build this with your control.
Neither in the demos - nor in the documentation we find something about how to build such a gauge.
All we found out is, that if Width and Height have different values everything gets "displaced"

Could you please tell us if both (hori - linear / 180* radial) is impossible - or if we simply missed somethin?

Regards

Manfred

Greetings,

I am trying to customize the background of the RadGauge control. Ironically, I stumbled upon Bill's unanswered question here: http://www.telerik.com/community/forums/wpf/gauges/radguage-background.aspx#761772

I am having the exact same problem. How do you replace the default red/orange with a Brush?

Thank you,
Chad Campbell

Hello,

I am trying to figure out how to use the RadGuage control. Currently, I am trying to just change the Background of the gauge. The red/orange colors do not work with my application. How do I replace the default red/orange background with an ImageBrush?

The templates in the documentation found here (http://www.telerik.com/help/wpf/radial-gauge-customizing-appearance.html) do not seem to work. For instance, when I use the templates, the values disappear.

Thank you!

Can someone post the code to Databind the WPF RadGrid with an OpenAccess DataProvider?

I cannot get anything to work!

I am unable to find the support for the right hand Y axis, is it there? :)

Hi,
is there a way to disable the virtualization?
I need to perform calculations on rows that don't exist in the virtualizing panel.

Thanks,

Hello,
Is it possible to have a checkbox on a GridViewGroupRow?  What I need to do is when the grid is grouped togeter (by a date as example) the user needs to check a checkbox on the group row which will check all rows within that group as completed.  Is something like that possible?

Thanks,
Nate

Hi,

We are in process to evaluate the WPF treeview controls.
We need to applyOffice 2007 theme to the treeview control, how can we apply that.

If it is possible then how can i get the Office 2007 theme treeview.

Thanks,
