Syntax
'Declaration
Public Property DataMember As String
'Usage
Dim instance As ListObject
Dim value As String
value = instance.DataMember
instance.DataMember = value
public string DataMember { get; set; }

Property Value
Type: System.String
A data member from a multimember data source. The default value is Empty.
Remarks
Not needed if the data source has only one member.
Use the DataMember property to specify a member from a multimember data source to bind to the ListObject control. For example, if you have a data source with more than one table specified in the DataSource property, use the DataMember property to specify which table to bind to the ListObject control.
Examples
The following code example creates a DataSet with two DataTable objects and populates one of the tables with data. The code then sets the DataSource and DataMember properties of the ListObject to bind to the table that contains data.
This example is for a document-level customization.
Private Sub ListObject_DataSourceAndMember()
' Create a DataSet and two DataTables.
Dim ordersDataSet As New DataSet("ordersDataSet")
Dim tableCustomers As New DataTable("Customers")
Dim tableProducts As New DataTable("Products")
ordersDataSet.Tables.Add(tableCustomers)
ordersDataSet.Tables.Add(tableProducts)
' Add a data to the Customers DataTable.
tableCustomers.Columns.Add(New DataColumn("LastName"))
tableCustomers.Columns.Add(New DataColumn("FirstName"))
Dim dr As DataRow = tableCustomers.NewRow()
dr("LastName") = "Chan"
dr("FirstName") = "Gareth"
tableCustomers.Rows.Add(dr)
' Create a list object.
Dim List1 As Microsoft.Office.Tools.Excel.ListObject = _
Me.Controls.AddListObject(Me.Range( _
"A1"), "Customers")
' Bind the list object to the Customers table.
List1.AutoSetDataBoundColumnHeaders = True
List1.DataSource = ordersDataSet
List1.DataMember = "Customers"
End Sub
private void ListObject_DataSourceAndMember()
{
// Create a DataSet and two DataTables.
DataSet ordersDataSet = new DataSet("ordersDataSet");
DataTable tableCustomers = new DataTable("Customers");
DataTable tableProducts = new DataTable("Products");
ordersDataSet.Tables.Add(tableCustomers);
ordersDataSet.Tables.Add(tableProducts);
// Add a data to the Customers DataTable.
tableCustomers.Columns.Add(new DataColumn("LastName"));
tableCustomers.Columns.Add(new DataColumn("FirstName"));
DataRow dr = tableCustomers.NewRow();
dr["LastName"] = "Chan";
dr["FirstName"] = "Gareth";
tableCustomers.Rows.Add(dr);
// Create a list object.
Microsoft.Office.Tools.Excel.ListObject list1 =
this.Controls.AddListObject(
this.Range["A1", missing], "Customers");
// Bind the list object to the Customers table.
list1.AutoSetDataBoundColumnHeaders = true;
list1.DataSource = ordersDataSet;
list1.DataMember = "Customers";
}
