Description

The Microsoft.SharePoint.WebControls.TableResultControl class inherits from the Microsoft.SharePoint.WebControls.PickerResultControlBase class which provides functionality for EntityEditorWithPicker contsruction facilitating the searching of arbitrary data. Class heavily related to the use of this control are the Microsoft.SharePoint.WebControls.EntityEditorWithPicker class, the Microsoft.SharePoint.WebControls.PickerDialog class, and Microsoft.SharePoint.WebControls.SimpleQueryControl class.

TableResultControl functions by using a series of System.Collections.ArrayList properties, namely:

ColumnDisplayNames
ColumnNames
ColumnWidths

to produce a System.Web.UI.WebControls.Table object that can contains the results of a data query used with a PickerDialog.ResultControl.

Usage Scenario

The primary usage of TableResultControl is to provide strongly typed Table generation include formatting for classes that inherit from PickerDialog. When a class is inheriting from PickerDialog, new ArrayList object can be created within the class constructor by casting a TableResultControl type against the PickerDialog.ResultControl, allowing exposure of the described properties.

In the below example, the MyPickerDialog class is inheriting from the PickerDialog class. MyPickerDialog contains a parameterless constructor, however is calling the base constructor passing in a custom MyEntityEditor object which inherits from the EntityEditorWithPicker class and a custom MyCustomQueryControl object which inherits from the SimpleQueryControl class. Following, in the MyPickerDialog constructor, we are building the relevant ArrayList objects for the custom PickerDialog to use by casting with the TableResultControl type against the PickerDialog.ResultControl, allowing the required values to be exposed via their properties.

C# Code Example

public class MyPickerDialog : PickerDialog
  {
    public MyPickerDialog() : base(new MyCustomQueryControl(), new TableResultControl(), new MyEntityEditor())
    {
      ArrayList columnDisplayNames = ((TableResultControl)base.ResultControl).ColumnDisplayNames;
      columnDisplayNames.Clear();
      columnDisplayNames.Add("Name");
      ArrayList columnNames = ((TableResultControl)base.ResultControl).ColumnNames;
      columnNames.Clear();
      columnNames.Add("Name");
      ArrayList columnWidths = ((TableResultControl)base.ResultControl).ColumnWidths;
      columnWidths.Clear();
      columnWidths.Add("100%");
    }
}

VB.NET Code Example

Public Class MyPickerDialog
    Inherits PickerDialog
    Public Sub New()
        MyBase.New(New MyCustomQueryControl(), New TableResultControl(), New MyEntityEditor())
        Dim columnDisplayNames As ArrayList = DirectCast(MyBase.ResultControl, TableResultControl).ColumnDisplayNames
        columnDisplayNames.Clear()
        columnDisplayNames.Add("Name")
        Dim columnNames As ArrayList = DirectCast(MyBase.ResultControl, TableResultControl).ColumnNames
        columnNames.Clear()
        columnNames.Add("Name")
        Dim columnWidths As ArrayList = DirectCast(MyBase.ResultControl, TableResultControl).ColumnWidths
        columnWidths.Clear()
        columnWidths.Add("100%")
    End Sub
End Class
