[1] On Form Load Controls are flickering
[2] To Solve issue i have added below code :
      protected override CreateParams CreateParams
                CreateParams handleParam = base.CreateParams;
                handleParam.ExStyle |= 0x02000000;   // wS_EX_COMPOSITED
                //handleParam.ExStyle |= 33554432;
                return handleParam;
This seems to be have solved issue but then issue occurring in SfDataGrid is not working properly in Edit Mode
[a] In GridText Box Cursor in Blinking too fast
[b] In GridComboxbox cursor is working for first character only(i.e. only single character is working in search. )

[3] At First Instance form is taking much time to load.

Hi Avinash, 

Thanks for using Syncfusion products. 

 On Form Load Controls are flickering 
We have analyzed this scenario with SfForm with some controls like button, combobox, listview. Unfortunately we could not able to reproduce the issue at our end. Could you please provide any of the following? 
  1. List of controls used within the SfForm.
  2. Provide the details if you have any drawing customization related to SfForm.
  3. Simple video or sample with issue reproducible.
These would be more helpful for us to analyze further on these scenarios and to provide the solution at the earliest. 
At First Instance form is taking much time to load. 
[a] In GridText Box Cursor in Blinking too fast 
[b] In GridComboxbox cursor is working for first character only 

We could able to reproduce this scenario and created the separate incident for this query alone. Kindly log on to our support website to check further updates on it.
