calendar control very slow performance with multiple columns and rows

[Valentijn]

Hi

We are using a calendar control to display a full year like this:

<

 

 

telerik:RadCalendar Grid.Row="2" x:Name="calendarRange"

 

 

 

Columns="4" Rows="3" SelectionMode="Extended" ViewsHeaderVisibility="Visible"

 

 

 

Culture="nl-BE" />

We are not doing anything to it in code behind.

However the performance is very poor in this case. It takes about 15 seconds to display and the browser is acting strange (hanging for a while). Also after running it seams some memory is being leaked as visual studio complains about out of memory.

Did anyone experience this? We tried it on different machines with the same result.
Is this a known issue and is there anything we can do?

Best regards

Valentijn

Hi Valentijn,

Can you run the control in a clean solution and check if there are some performance bottlenecks regarding the control?

Hi

We have the same problem.

Our calendar has 4 columns et 3 rows.
It 's localized into a tab item. It's very slow to display it.
When we want to get another tab item, the navigator is blocked, the CPU raise at maximum.
We have to wait to wait 20 seconds to continue.

Have you news about this problem ? 
It is possible to fix it please ?

Thank you 

Mathieu

Hi Valentijn,

Can you try loading the control apart from the TabControl. You can also share a code sample of the issue so we can investigate the problem and provide you with work around?

Hi
 
The problem appears when the calendar Row number is 3.
It takes many seconds to display it.
When I leave its tabs item, it take many second to change the tab item display.
I return to my Calendar TabItem then i leave it again : it takes more time at each leaving.

As work around, in code behind i had to do this when i leave my calendar tab item  :

calendarYearView.Columns = 1;
calendarYearView.Rows = 1;

Then when i return to my calendar tab item i do this in code behind :

calendarYearView.Columns = 4;
calendarYearView.Rows = 3;

Thank you
