Disable Scrolling for Panning in Grid

[Alan]

Hi, How can I disable grid scrolling associated with a panning gesture? I would like it just to work when using the grid's scrollbar. So, while a user is panning, e.g. panning vertically up, I do not want the grid to scroll.

Thanks!

Hi, Alan,

Please set the RadGridView.EnableGestures property to false. In addition, make sure that the EnableKineticScrolling property is also set to false. Thus, you wouldn't scroll the view with moving the mouse with left button down.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Thanks for the reply! I need to handle panning but in a different way, other than scrolling. So, it needs to be enabled as a gesture. Is there a way  to disassociate scrolling from the panning or to override the behavior that panning has on the grid?

Thanks again!

Hello, Alan, 

If the pan gesture is enabled and you want to plug into the default logic, first make sure that the EnableKineticScrolling property is set to false. Thus, you will prevent the scrolling.

Then, you can create a derivative of RadGridView and override its OnPanGesture method. There, you can introduce the desired logic you need.

An alternative approach is to create a custom TableViewDefinition and override its CreateViewUIElement method where you can replace the default GridTableElement with a custom one: 

        public class CustomTableViewDefinition : TableViewDefinition
        {
            public override IRowView CreateViewUIElement(GridViewInfo viewInfo)
            {
                return new CustomGridTableElement();
            }
        }

        public class CustomGridTableElement : GridTableElement
        {
            protected override Type ThemeEffectiveType     
            { 
                get    
                { 
                    return typeof(GridTableElement);     
                }
            }
             
            protected override void OnPanGesture(PanGestureEventArgs args)
            {
                //TODO
                base.OnPanGesture(args);
            }
        }

Then, in the Designer.cs file replace the default TableViewDefinition with your custom one.

Should you have further questions please let me know.
