Examples

The following code example demonstrates how to use the WebDescriptionAttribute attribute to assign a ToolTip to a property on a Web Parts control. The custom UserJobType property is given the ToolTip "Select the category that corresponds to your job." to display in the PropertyGridEditorPart control. This example is part of a larger example found in the PropertyGridEditorPart class overview.

[Personalizable(), WebBrowsable(), WebDisplayName("Job Type"), 
  WebDescription("Select the category that corresponds to your job.")]
public JobTypeName UserJobType
{
  get
  {
    object o = ViewState["UserJobType"];
    if (o != null)
      return (JobTypeName)o;
    else
      return _userJobType;
  }

  set { _userJobType = (JobTypeName)value; }
}

<Personalizable(), WebBrowsable(), WebDisplayName("Job Type"), _
  WebDescription("Select the category that corresponds to your job.")> _
Public Property UserJobType() As JobTypeName
  Get
    Dim o As Object = ViewState("UserJobType")
    If Not (o Is Nothing) Then
      Return CType(o, JobTypeName)
    Else
      Return _userJobType
    End If
  End Get
  Set(ByVal value As JobTypeName)
    _userJobType = CType(value, JobTypeName)
  End Set
End Property

Remarks

The PropertyGridEditorPart control provides a generic user interface (UI) that enables users to edit custom properties on WebPart and server controls placed in WebPartZoneBase zones. The editing UI is provided for properties that are marked in the source code with the WebBrowsable attribute (from the WebBrowsableAttribute class). When a property is marked with this attribute, a PropertyGridEditorPart control creates the editing UI based on the type of the property, and uses a PropertyDescriptor object if needed to convert the value in each editing control to the type of the property.

The WebDescription attribute (from the WebDescriptionAttribute class) allows you to specify the ToolTip that appears with each control in the editing UI when the mouse pointer is positioned over the control.
