Represents a design-time editor sheet for the properties of a resource expression in the UI of a designer host at design time.
Assembly: System.Design (in System.Design.dll)
Initializes a new instance of theclass.
Gets or sets the key that matches the filename for the resource in the project's global resource folder.
Gets a value that indicates whether the resource expression string is valid.(Overrides ExpressionEditorSheet.IsValid.)
Gets or sets the name of the resource, which is used as a key to find the resource value.
Gets the service provider implementation that is used by the expression editor sheet.(Inherited from ExpressionEditorSheet.)
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
Returns a resource expression that is formed by the expression editor sheet property values.(Overrides ExpressionEditorSheet.GetExpression().)
Serves as the default hash function. (Inherited from Object.)
Returns a string that represents the current object.(Inherited from Object.)
The visual designer uses the ResourceExpressionEditor class with the class to select the individual properties of a resource reference expression, and to combine the selected resource expression property values into a resource expression.
The ConnectionStringsExpressionEditor.GetExpressionEditorSheet method returns a object. In the expressions dialog box, when you select a control property and bind it to a resource expression, the visual designer calls the GetExpressionEditorSheet method. The visual designer uses the returned object to prompt for the ClassKey and ResourceKey properties. Once the resource expression properties are selected, the visual designer calls the GetExpression method to combine the properties into a resource expression string.
The ResourceKey property must be specified in a resource expression; it indexes the resource value. The ClassKey property is optional. It references the class key or file name that defines the resource in the global resources folder.
In a Web site project, add a new resource file named Strings.resx to the App_GlobalResources folder.
Add a string named myLinkText to the Strings.resx resource file, and set the value to the text for a HyperLink control. For example, set the myLinkText string value to This is a link.
In an ASP.NET Web page, add a HyperLink control.
In the property grid for the Hyperlink control, click Expressions, and click the ellipsis button (...) to display the expression binding dialog box.
Select the Text property of a control, and set Expression Type to the Resources expression type. The visual designer displays the resource expression properties defined by the object.
Set the Expression Properties as follows:
Set ClassKey to Strings, the class name for the compiled Strings.resx resource file.
Set ResourceKey to myLinkText, the string name in Strings.resx.
The visual designer uses the ResourceExpressionEditor object to assign the resource expression for the Text property. The following aspx source shows an example of a property value set using a resource expression:
