Crystal reports windows forms viewer the handle is invalid




















The first level of customization is to show or hide the individual components of the viewer. The group tree on the left side can be shown or hidden via the DisplayGroupTree Boolean property. The toolbar works the same way via the DisplayToolbar property.

In addition to hiding the entire toolbar, each button or button group on the toolbar has corresponding properties that allow them to be individually hidden or shown. These properties can be found in the property browser or accessed via code. The names should be self-explanatory. It tends to not add a lot of value and end up more of an annoyance than anything.

A trick to hide this status bar is to drop a panel control onto the form and drop the viewer onto the panel. Set the viewers Dock property to Fill so that the viewer always sizes itself to the size of the surrounding panel.

Then set the DockPadding. Bottom property of the viewer to This sizes the height of the viewer to 20 pixels more than the panel, effectively hiding the status bar below the extents of the panel. Keep in mind that any methods and properties that need to be accessed from the report viewer after youve done this need to be accessed via the panel objects controls collection. The Report Viewer is shown here with its status bar hidden. Another property that can be used to change the behavior of the report viewer is the EnableDrillDown property.

Setting this Boolean property to false disables the user from performing any drill-down operations. Finally, the SelectionFormula and ViewTimeSelectionFormula properties can be used to create and append filters to the report.
