Add Method (ObjectListFieldCollection)

Adds a field to the end of the collection.

public void Add(
   System.Web.UI.MobileControls.ObjectListField field
)

Parameters

• field
  The ObjectListField to add to the end of the collection.

Remarks

This method is not available in the read-only IObjectListFieldCollection interface.

Adding a field to the field collection of an object list changes the data-binding behavior of the control and requires you to bind data to the control again.

Example

The following example demonstrates how to use the Add method to add a field (ListField1) to the end of the ObjectListFieldCollection.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    If Not IsPostBack Then
        
        Dim arr As ArrayList = New ArrayList()

        arr.Add(New Task("Verify transactions", "Done"))
        arr.Add(New Task("Check balance sheet", "Scheduled"))
        arr.Add(New Task("Send report", "Pending"))

        'Associate and bind the list to the array.
        ObjectList1.DataSource = arr
        ObjectList1.DataBind()
 
        ObjectList1.AutoGenerateFields = False
        Dim ListField1 As New ObjectListField()
        ListField1.DataField = "TaskName"
        ListField1.Title = "Task Name"
        ObjectList1.Fields.Add(ListField1)
        ObjectList1.DataBind()
      
   End If
   

[C#]

public void Page_Load(Object sender, EventArgs e)
{
  public void Page_Load(Object sender, EventArgs e)
{
  
   If (!IsPostBack)
   { 
   ArrayList arr = New ArrayList();

   arr.Add(New Task("Verify transactions", "Done"));
   arr.Add(New Task("Check balance sheet", "Scheduled"));
   arr.Add(New Task("Send report", "Pending"));

   //Associate and bind the list to the array.
   ObjectList1.DataSource = arr;
   ObjectList1.DataBind();

   ObjectList1.AutoGenerateFields=false ;
   ObjectListField ListField1 = new ObjectListField();
   ListField1.DataField = "BookName";
   ListField1.Title = "BookName";
   ObjectList1.Fields.Add(ListField1);
   ObjectList1.DataBind();
   }
}
