Implements
_XDocument2.GetDataVariable(Int32)
_XDocument.GetDataVariable(Int32)
Remarks
If the variable is not defined or is empty, the GetDataVariable method will return an empty string. To set a variable, use the SetDataVariable method.
Note
InfoPath only supports using the initialView variable, which is the variable used to specify the initial view displayed when a form is opened. The number of this variable is always 1, and its value must be the name of a view within the form.
Important
This member can be accessed only by forms running in the same domain as the currently open form, or by forms that have been granted cross-domain permissions.
Examples
In the following example, the GetDataVariable method of the XDocument object is used to return the value of the first variable:
string variable1;
variable1= thisXDocument.GetDataVariable(1);
