Hi,

Having a bit of anxiety attack finding out users are experiencing slow launch times on a Office plugin using Winforms.
Initially I thought is may be due to something I did, but found out it's all in the Telerik object initializations.
The delays are to the point that the solution is not shippable and I'm in a bind unless I can bring these long init times down.
Delays of 6 sec to 30 sec are being reported by many test users.

I put in some code to measure timings, which brought me to my conclusion.
I don't connect up the datasources until later, the long init times are with no data connected. Also I moved all of the ResumeLayout() and performLayout() calls to the end of the InitializeComponent() block.

    
            [debug_timing] = 

            [0s 0m] AddinModule_AddinInitialize_Start 
        
            [0s 31m] AddinModule_AddinInitialize_End 
        
            [0s 0m] Display Form Request - Zeroed 
        
            [0s 0m] InitializeComponent start 
        
            [6s 515m] InitializeComponent end 
        
            [0s 62m] Form Loading 
        
            [0s 0m] Lookup Data Start 
        
            [0s 671m] Lookup Data End 
        
            [1s 718m] Display Form

Put in some more detailed timing calls, and found:

Of this excessive initialization time:
Approx 40% of the time is spent creating the Teleric controls and the BeginInits() , From <<<a>>> to <<<b>>>
Approx 60% pf the time is spent in the Teleric EndInit() calls, From <<c>> to <<<d>>>

    
            private void InitializeComponent() 
        
            { 

            this.SuspendLayout(); 
        
            <<<< a >>>>> 
        
            new Telerik.WinControls.UI....(); 
        
            .. 
        
            .. 
        
            ((System.ComponentModel.ISupportInitialize)....BeginInit(); 
        
            <<<< b >>>>>> 
        
            ... 
        
            setup properties for each forms object 
        
            .. 
        
            <<<<< c >>>>> 
        
            ((System.ComponentModel.ISupportInitialize)....EndInit(); 
        
            <<<<< d >>>>> 
        
            .. 
        
            .. 
        
            Moved all the ResumeLayout() and performLayout() calls here 
        
            }

I love the product, and chose it primarily to provide a UI that is in line with the Office suite. I've noticed other users experiencing similar issues.

Any thing else I can try?

Thanks.
Ron
