GridControl and its Parent ScrollBar scrolls together when mouse scrolled.

[Harinarayana]

Hi,

I am using GridControl in my app. GridControl will display Vertical Scroll bar after loading items.

At the the same time as items are more in UI, GridControl's parent, Form control also has its own ScrollBar.

When we scroll mouse on top of GridControl, both GridControl and Form's ScrollBar scrolls together.

If we scroll on top of ListView (Default win form control), only ListView ScrollBar scrolls. If we move mouse control outside, then Form's ScrollBar moves.

I need same behavior in GridControl. Could you pls help me to solve this issue?

Regards,

Harinarayana.

Hi Harinarayana, 

Thanks for using Syncfusion product. 

You can avoid scrolling of GridControl’s parent by overriding its parent’s OnMouseWheel method and allow mouse wheel if its child element is empty at the mouse over point. Here we have restricted for Form’s mouse wheeling while scrolling is done in GridControl. 

protected override void OnMouseWheel(MouseEventArgs e) 

{ 

    var child = this.GetChildAtPoint(e.Location); 

    if (child == null) 

        base.OnMouseWheel(e); 

}
