ThinkGeo.MapSuite.WindowsPhoneCore.GradientStyle

Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.

<!– Class –> This gradient style is a new style with the concept of GradientBrush. By specifying the LowerValue and its color, as well as the UpperValue and its color, we can set the color of each feature based on a column value using linear interpolation.

Public Methods

Draw(IEnumerable<BaseShape>, GeoCanvas, Collection<SimpleCandidate>, Collection<SimpleCandidate>)

This method draws the shapes on the canvas you provided.

Remarks

This method is the concrete wrapper for the abstract method DrawCore. In this method, we take the shapes you passed in and draw them on the canvas you provided. Each style (based on its properties) may draw each shape differently.

As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

GetRequiredColumnNames()

This method returns the column data for each feature that is required for the style to properly draw.

Remarks

This method is the concrete wrapper for the abstract method GetRequiredColumnNamesCore. In this method, we return the column names that are required for the style to draw the feature properly. For example, if you have a style that colors areas blue when a certain column value is over 100, then you need to be sure you include that column name. This will ensure that the column data is returned to you in the feature when it is ready to draw.

In many of the styles, we add properties to allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore we read that property and add it to the collection.

As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

Return Value

Protected Methods

DrawCore(IEnumerable<Feature>, GeoCanvas, Collection<SimpleCandidate>, Collection<SimpleCandidate>)

This method draws the features on the canvas you provided.

Remarks

This virtual method is called from the concrete public method Draw. In this method, we take the features you passed in and draw them on the canvas you provided. Each style (based on its properties) may draw each feature differently.

When implementing this virtual method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties to allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.
