VisualizationLayer Items Virtualization and ShapeFill

[Matthes]

Hello everyone,

I have a VisualizationLayer with ShapeFills set on the layer level by using

<telerik:VisualizationLayer.ShapeFill>

...

</telerik:VisualizationLayer.ShapeFill>

​

If the ShapeFill of the MapShapedata is changed in code (for example by selecting some elments from a list and then call .UseSelectedFill() ) and then a MapItemsRequest happens, the original ShapeFill of the items will be restored instead of keeping the "manually" set ShapeFill. How can I make them keep their ShapeFill ?

Hello Matthes,

When you use the public methods UseHighlightFill(), UseRegularFill(), UseSelectedFill(), they set locally the ActiveShapeFill property which is used in the ShapeTemplate. Here are the methods implementations:

    /// <summary>
        /// Use highlight fill and stroke settings.
        /// </summary>
        public void UseHighlightFill()
        {
            if (this.HighlightFill != null)
            {
                this.IsHighlighted = true;
                this.ActiveShapeFill = this.HighlightFill;
            }
        }

/// <summary>
        /// Use regular fill and stroke settings.
        /// </summary>
        public void UseRegularFill()
        {
            if (this.ShapeFill != null)
            {
                this.IsHighlighted = false;
                this.IsSelected = false;
                this.ActiveShapeFill = this.ShapeFill;
            }
        }

    /// <summary>
        /// Use selected fill and stroke settings.
        /// </summary>
        public void UseSelectedFill()
        {
            if (this.SelectedFill != null)
            {
                this.IsSelected = true;
                this.ActiveShapeFill = this.SelectedFill;
            }
        }

So in order to use ActiveShapeFill set by you in the full lifetime of a shape data object, you need to set this property to your value and set the other three properties ( SelectedFill, HighlightFill, RegularFill) to null.

Please let us know if this works in your scenario.
