WPF Application Startup Turns Black waiting and Actual Window Appears

    Question

  • Hi,

    I have developed a Complex WPF Application with Header, Footer, LeftMenu and RIght Pane all with User Controls. SOme of the Data is loading dynamically. Everything Works fine as i expected. The only thing killing me is ..... When i Run my WPF App (F5), the window turns black and then the actual window appears. I tried applying SPlash Screen but still it appears.

    I am thinking that, if the black screen is because of Loading , then i would like to show some processing screen or symbol to avoid that fully black window.

     

    Please Advice,

     

    Thanks in advance,

    San

  • I don’t think this would be related to loading the controls, but maybe the data that you are displaying with the controls.  Could this be it, loading a lot of data at startup?  You may want to consider loading all your data on a thread separate from the UI thread. 

     

    Here are a couple of links that may help.  The BackgroundWorker class and here is a good write up Build More Responsive Apps With The Dispatcher

     

    Hope this helps.  It may also be helpful to see some code samples of what you are doing at startup.
