Hi,

I'm trying to create a 3D Dougnut Chart, but are having troubles with the Series Mapping. Using the code below, I get the legend to show color coded items equal to the amount of rows in the table. But nothing else displays.

 

Any help would be much appreciated. Not really sure how the charting works.

Thanks,

Henry

2) What's the name of the left control in the demo app(which lists particular control's demos)? It looks like treeview, but I liked it's effects and want to use it in my application. Thanks.

Hi there !
I have one window control wich holds two grids( one wich will be static - with a banner ) and the other will have two different user controls ( one for the list case and the other for adding/ editing data ) . I am defining several commandbindings & keybinds in order to have a fully functional keyboard shortcut system . The problem appears when I use the RadNumericUpDown control . When I insert a decimal value or other, my window control looses the focus; I have compared the state of the focus before and after using the numericupdown and I can see that the window focus status change ( from true to false )... I guess this happens right when i use the numericupdown control ... Any ideia / suggestions ?

Thanks,
Ivan Frias

Hi,

Where can I find more detailed samples of using various features of TreeView control, samples present in demo are not enough.

Hello,

Is there an event that is raised when a column is resized?  If not, do you have any suggestions about how to get notified whenever a column is resized?

Thanks,

Hi

Can we use rad gauge in web-applications?

I'm using version 1.0.1.0 (Q2 2008 we believe) of the TreeView control. The hierarchy represented in the control is not bindable throughout, so we are forced to manually refresh it from time to time, and we also need to re-select the selected item after a refresh. The code is a bit complicated, but it seems to work well enough. It's called after PlansTreeView.Items.Refresh().


We also need to have some of the nodes sorted, and that code works well and seems simple enough:


The trouble is that once a node is sorted, I can no longer refresh it (regardless of my Reselection - PlansTreeView.Items.Refresh() just does nothing). Is there something going on in the control that disables refreshing once I have it sorted? Or are there other approaches I should be taking towards refreshing the tree?
