Tracking number of open raddesktop alerts

Hi I want to show only upto 3 desktop alerts at any given time. Some alerts have autoclose options while others do not. As such before displaying an alert, I need to check how many are open. I tried using the desktopalertmanager but running into null exception errors

Dim

iDesktopAlertManager As DesktopAlertManager
Dim value As IEnumerator(Of RadDesktopAlert)
value = iDesktopAlertManager.GetRegisteredAlerts()

I stepped though the code and the iDesktopAlertManager is nothing which causes a null exception error. I am not fully aware of the DesktopAlertManager.

This is similar to the code sample on your reference pages so not sure what I am doing wrong here...

Disable popping up the calendar in a DateTime cell

If I set the Format to "Time" I see no need for the Calendar button to show up in the cell. I basically want a cell that only has time in it. How can I disable showing the calendar button?

Check Box on Ribbon

I have a series of check boxes on my rad ribbon bar which I use to quickly filter a grid. I am handling the Click event of the RadCheckBoxElement, this calls a method to Refresh the grid, the problem is that the checked value of the control is not being passed correctly to the toggle state property, e.g. when it's ticked it passes false, when it's unticked it passes true.
I know I am doing something stupid, but can somebody please advise what...

Resources

I've attached a screen dump. Can the telerik RadScheduler be customized as such?

I have positions or vacancies as the vertical heading and horizontal heading as time of the day, which display a 24 hr day.

Memory leak when using GridViewComboBoxColumn

Hello,

I have come across a problem of memory leak when using GridViewComboBoxColumn.

I used the Memory Profiler program to ditect the problem.

I have opened a form with a GridView control, which contains a GridViewComboBoxColumn.

Edited 5 cells of a GridViewComboBoxColumn type and took a snapshot of the memory,

The RadPropertyValue has used 11,500,000 bytes.

Edited 5 cells added of a GridViewComboBoxColumn type and took a snapshot of the memory,

The RadPropertyValue has used 42,300,000 bytes.

The attached files display the result.

After closing the form I took another snapshot which showed that the instances where still indirectly rooted by an EventHandler.

This problem is causing the users to use a large amount of memory.

Dispirit for an answer.

Dynamically bestfit columns as user scrolls a grid

I would like to bestfit all the columns dynamically as user scrolls a grid vertically.
I don't know if this is at all possible, since there seems no event that is called in grid when user scrolls it vertically.

I am using Q1 2008 SP1 radgridview.

Thanks
Sunil
