Minimized form could not be restored

[Plotnikova]

Hello,

I've a the following problem on windows 7 and Windows vista:
if my application has alredy loaded a syncfusion control and then the user minimized the form. After that the application could not be restored from taskbar any more.

Is this behavior known for you?

Here is the message log:

Hi,

I've found out why my application could not be restored from a taskbar.

In ApplicationIdle event handler I update the state of some controls and get some information from syncfusion grid. If i remove this code my application runs well.

How is it possible to use syncfusion grid ind idle event handler?

Thank you in advance

Hello Selva Ganapathy K,

thank you for reply.
I have some controls that register application idle event. In this handler they do some update of for example enabled flags and calls some methods of syncfusion grid. If the application is minimized coltrols are getting this event and by clicking on the taskbar to restore the form nothing happens.
I've added the check that the code should run if the application is not minimized.
But may be i use the grid not properly.

Best regards
