BUILDING APPLICATIONS WITH WINDOWS CONTROLS
OnPageLayoutReplaced event will be triggered whenever a document is
loaded into the PageLayoutControl.
private void axPageLayoutControl1_OnPageLayoutReplaced(object sender,
ESRI.ArcGIS.PageLayoutControl.IPageLayoutControlEvents_OnPageLayoutReplacedEvent
e)
{
// Load the same preauthored map document into the MapControl.
axMapControl1.LoadMxFile(axPageLayoutControl1.DocumentFilename,null,
null);
// Set the extent of the MapControl to the full extent of the data.
axMapControl1.Extent = axMapControl1.FullExtent;
}
Setting the TOCControl and ToolbarControl buddy controls
For the purpose of this application, the TOCControl and ToolbarControl will
work in conjunction with the PageLayoutControl, rather than the MapControl.
To do this the PageLayoutControl must be set as the buddy control. The
TOCControl uses the buddy’s ActiveView to populate itself with maps, layers,
and symbols, while any command, tool, or menu items present on the
ToolbarControl will interact with the buddy control’s display.
1. In the Form_Load event enter the following after the load document code:
private void Form1_Load(object sender, System.EventArgs e)
{
// Load a preauthored map document into the PageLayoutControl using
// relative paths.
string fileName =
@"..\..\..\..\..\..\..\..\Data\\ArcGIS_Engine_Developer_Guide\Gulf of St.
Lawrence.mxd";
if (axPageLayoutControl1.CheckMxFile(fileName))
{
axPageLayoutControl1.LoadMxFile(fileName,"");
}
// Set buddy controls.
axTOCControl1.SetBuddyControl(axPageLayoutControl1);
axToolbarControl1.SetBuddyControl(axPageLayoutControl1);
}
2. Build and run the application. The map document is loaded into the
PageLayoutControl, and the TOCControl lists the data layers in the map
document. Use the TOCControl to toggle layer visibility by checking and
unchecking the boxes. By default, the focus map of the map document is
loaded into the MapControl. At this point the ToolbarControl is empty because
no commands have been added to it. Try resizing the form, and note that
the controls do not change size.
