memory defragmentation

Hello,

we have programed a class library, that has too big memory usage. We have disposed explicit all unmanaged resources like files. We have already taken a look with a memory profiler and its seems the problem is that the GC doesnot clear up the memory or the memory gets defragemented (there are a lot of small pieces of memory and .net allocates always new memory instead of reusing the small free pieces of memory). The process goes up to 2 GB RAM usage, but such amount of memory is never used / needed.

Note: Its a multi-threaded application.

I am out of ideas, what I can try to get the process smaller. All ideas will be appreciated!

Thanks in advance !!

Best regards

Andreas

MDI merging RadToolbar & RadMenu

I've seen some posts about merging toolbars. My impression is that it can be done, but not something that's currently built in. Am I correct? If it is built in, could someone point me to the necessary steps?

I have this scenario: I have a MDI form that opens MDI child forms as document windows. Each MDI child has its own RADToolbar that I'd prefer to have merged with the MDI parent's RADToolbar like VS does.

Thanks

Seeing panels with odd corners

I'm using a number of RADPanels & RADSplitter panels. I'm seeing the same display for both. If I set the shape to a round rectangle with 10 degree radius corners, I still see a 90 degree white corner. The borders look like they're properly creating the radius that I'm looking for, but I don't know how to get rid of the 90 degree white corners.

In addition, I'm seeing a flakiness with shapes being retained. Very often all of the objects lose their formatting when a form or VS08 is reopened. I'm not sure what does this, and more importantly what I need to do for it to stop because reformatting forms 2,3,4,5x a day is beyond annoying at this point.

Thanks

RadLabel size is zero without a parent

Hello,

I'm using the Dec 3rd version of the WinForms components. After upgrading some of our forms don't look right. What I determined was a RadLabel created dynamically has a size of (0, 0) until it is assigned to a container. Is there a way to know the size of the RadLabel before it has a parent? Our current logic relies on the size of the labels to build the container form so it is broken because of this change.

Here is some sample code to show the issue:

    
            RadLabel rl = new RadLabel(); 
        
            rl.Text = This is a test; 
        
            rl.Location = new Point(20, 20); 
        
            // rl.Size is (0,0) at this point 
        
            this.Controls.Add(rl); 
        
            // now rl.Size is correctly showing (67, 14) in this test
