Hi Narendra,
Docking Manager loads the docking windows properties after the Form Load event. If you want to set or get the values for docking windows during application startup, you could use the statement within the
NewDockStateEndLoad event. This event will trigger at the end of the Form Load event. Please take a look at this attached sample and let me know if this meets your requirements.
We appreciate your interest in Syncfusion Products.
Thanks,
Vijay.
