When i set the RadRichTextBox's background property in layoutmode property is normal,the background is effective.
But when the LayoutMode is paged the background property is invalid,and look like something shut out.

I want to set the background property in layoutmode is paged can be effectove,please help me(⊙_⊙)?

Greeting.

Can you give any information about Radchart performance at huge datasets.
I want to display ScatterPlot with 150.000 point inside.
I cannot use SamplingThreshold, because i must show all points.
(if i have 500x500point area, in bad scenario i must show 500*500=250.000 points)


I try to create some tests.
With SamplingThreshold=200, when i add to datasource my dataset, it want 4 seconds or so.
And after this control painted without any pause.
With SamplingThreshold=5000 i wait  10-15second before control painted.
With SamplingThreshold=25000 i wait 100-150second before control painted.
With SamplingThreshold=100000 i wait 10 minutes... no way... application struck.
I try disable animation, disable autorange etc etc etc, nothing help.

Can Radchart potentially show 150.000 point, or it just impossible ?
If it possible, may be any example with big set available ?

Best Regards
Serg

Hi Telerik,

I need to 'do stuff' when user switches from one radpane to another.

I've looked at RadPane.GotFocus() and RadPane.GotKeyboardFocus() but they only fire once I activate contents of the RadPane -- i.e. when I click the pane header, I do not get the desired notification.

Do you have a recommendation on what to 'watch'?

Thanks,

Anders, Denmark

Thanks

How can I achieve this? I don't want to define a cell template so I rather stick with GridViewCheckBoxColumn but I don't see the Command property.

hi,

can you please let me know that is there any other ResultFormatString except "{}{0:c}"

Regards,

Hi.. I have grid at the bottom of a form. When a user clicks on the header to filter the fitler menu extends below the form and off the screen. And the user can't select the options.
How I can make the menu open 'up' - instead of down. Or make the menu appear totally on the form?
thanks in advance

Every time I use RadWindow e.g:

RadWindow.Alert(new DialogParameters()
            {
                Content = "Hello"
            });

i get following binding error:

System.Windows.Data Error: 5 : Value produced by BindingExpression is not valid for target property.; Value='<null>' BindingExpression:Path=(0); DataItem='RadWindow' (Name=''); target element is 'WindowHostWindow' (Name=''); target property is 'Title' (type 'String')

I even tested it on visual studio base wpf app template - still the same error.

Is there any way to fix it ?

Hi,

I'm using VS2008 and Telerik 2011.3.1220.35 and with one of my RadGridView I have a problem :(

The second column of my grid view is a GridViewToggleRowDetailsColumn and when I click on the plus sign, my application fall in an infinite loop and I receive the following message:
