Where to put long-running startup code when using SplashPanel?

[deanwiles]

I would like to display a Splash screen at startup to display an image and some status info during our initial database operations, which can take a few seconds. 

Based on the Syncfusion docs and samples I think I need a SplashControl with a SplashPanel that hosts the image and status label field. Is that correct?

Anyway, if I place my database initialization code in Form1_Shown() or splashControl1_SplashDisplayed(), then the SplashPanel's label & image fields don't get displayed until after my DB init code completes. 

Is there a working example of a SplashControl or SplashPanel displayed during some long-running initialization code?

There was some discussion of a related issue in How to load a "GIF" image in SplashControl or SplashPanel ?, but the sample code is no longer available.

Thanks,

Dean

Hi Dean 

 

Thank you for using your syncfusion products. 

 

We have checked the reported requirement with SplashPanel/Splash control, but we are unable to predict what your exact requirement is and what does your meant about long operation at your end. If possible, could you share us your video that shows your problem, so that we could able to check at our end and provide you the prompt solution accordingly.

Attached is a sample that demonstrates the problem. I have placed a call to Thread.Sleep(3000); to simulate the delay caused by our database initialization.

Below is what the app looks like during the startup code. The blue background of the splash screen is displayed, but not the label or image controls.

It appears that I should not put any long-running code in the Form1_Shown() or splashControl1_SplashDisplayed() events, so I'm hoping you can indicate whether I am using the SplashControl/SplashPanel correctly or what event I should hook into for my long-running database initialization code.

Thanks.

Hi Dean, 

Thanks for your patience, 

We have checked your query” where to put long-running startup code when using splash panel”.You can achieve your requirement using the “TimerInterval” Property.Please check the sample and the help documentation for your reference. 

this.splashPanel1.TimerInterval = 5000; 

Sample Link: https://www.syncfusion.com/downloads/support/directtrac/general/ze/SplashPanel-439455542 

Documentation Link: https://help.syncfusion.com/windowsforms/splash-panel/display-settings#time-interval 

Please let us know if you have any other concerns.

Hello Bharathi,

Thank you for your reply, but adding the line below has no effect, as the SplashPanel TimerInterval already defaults to 5000 milliseconds.

this.splashPanel1.TimerInterval = 5000; 

I don't think you are understanding my problem. The call to Thread.Sleep(3000); was there to simulate the delay caused by our database initialization. In the modified sample code, it appears you removed that call so the modified sample no longer represents the problem and does not offer a solution.

FYI, I just added a timer control to the form and set the timer event to run once after Form1_Shown(). When the timer event fires I disable the timer, perform the long-running code, and then hide the SplashControl.

The updated sample code is attached.
