ShowModes makes it possible to hide elements for some reports. Leave ShowModes blank for the element to always appear. Set it to None and it will be hidden. (You can make it appear later with an Action.ShowElement.) Set it to your own string value to have it appear only when the report's ShowModes includes that value. ShowModes can contain multiple, comma-delimited values.
Built-in ShowModes can be set on individual elements, without having to set a corresponding value in the report-level "Default ShowModes" list.To use built in ShowModes, set it to one of the pre defined values like
"rdBrowser","rdExport","rdExportPdf" etc from the dropdown list.
eg - Set ShowModes = "rdBrowser" for elements that should only appear in the browser and should be excluded from exports.Set ShowModes = "rdExport" for elements that should be exported but not shown in the browser.
