MGDwgDataSources.setDataSource

Syntax

boolean setDataSource(string dataSource) 

Description

Sets the DWG data source name that establishes a connection between Autodesk MapGuide Server and the data provider.

If this method is successful, it automatically sets the layer's rebuild flag to True. See setRebuild for more information.

When changing the DWG data source, several other properties may also have to be updated. These properties include Dwg, KeyTable, KeyColumn, KeyColumnType, NameTable, NameColumn, UrlTable, UrlColumn, and LayerFilter.

Note that this method does not work during a busy state. For additional information about the busy state, refer to "Handling Busy State and Map Refresh" in the Autodesk MapGuide Developer's Guide.

Parameters

dataSource - The name of the data source.

Returns

boolean - Returns True if successful.

Error Codes

Example

This code is designed to work with the 1stfloorplanEx6.mwf file used by the Filter DWG Layers example:

function setProperties()
{
   // Get the map and selected features
   var map = getMap();
   var mapSel = map.getSelection();
   // Use the single map layer Floor Plan
   var mapLayer = map.getMapLayer("Floor Plan");
   // Get DWG data source object for the layer
   var mapLayerSetup = mapLayer.getLayerSetup();
   var dwgMapLayerDataSource = mapLayerSetup.getDwgDataSources();
   dwgMapLayerDataSource.setDataSource("newDataSource");
}
