Hello

I wanted to know:

1) When I open the demo project with VS 2008 Professional Edition with SP1, VS crashes.any ideas? I'm using vista sp1, + telerik 2008 q3. I tried running vs with admin but didn't help

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,

I am getting an exception whenever I try to resize any column of an empty gridview. Is this a known issue?

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,

Joel

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?

Hello,
I need export radGrad to Excel file.

This is a code:

gv.ExportSettings.FileName = getFileName();
gv.ExportSettings.ExportOnlyData = true;
gv.ExportSettings.IgnorePaging = true;
gv.ExportSettings.OpenInNewWindow = true;
gv.MasterTableView.Style["text-align"] = "left";
gv.MasterTableView.ExportToExcel();

 

The problem: text-align of data in cells in excel file is different! One column aligned left, other - right. But in radGrid all aligned left.
I tried set style gv.MasterTableView.Style["text-align"] = "left"; but this doesn't solve my problem.
How can I set style for table cells???

P.S.
I found on the forum screenshot of excel table with a similar problem (last column aligned left and other right):
http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/export-to-excel-number-problems.aspx

Thanks a lot.

Hi guys,

Great work on the TreeView. Would love for you to implement a CheckChildNodes proprty like the ASP.NET TreeView has.

Cheers
