The ParameterCollectionEditor class provides a user interface for editing the Parameter elements of the ParameterCollection object at design time, as specified by one of the Parameters properties. The Parameters properties include the DeleteParameters, FilterParameters, InsertParameters, SelectParameters and UpdateParameters properties of the ObjectDataSource, SqlDataSource, and other data source controls.

The ParameterCollectionEditor is invoked by selecting the ellipsis () button on one of the Parameters properties in the Properties grid of the visual designer.

The EditValue method edits the Parameter elements of the ParameterCollection for the associated data source control. The GetEditStyle method gets the editing style that is associated with this editor.

The following code example shows how to use the EditorAttribute attribute to associate the ParameterCollectionEditor and UITypeEditor (the collection editor base class) classes with a SelectParameters property in a custom control.

private ParameterCollection selectParams;

// Associate the ParameterCollectionEditor with the SelectParameters. 
public ParameterCollection SelectParameters
        // If there is no selectParams collection, create it.
        if (selectParams == null)
            selectParams = new ParameterCollection();

        return selectParams;
    set { selectParams = value; }
} // SelectParameters
