DataGrid::SetDataBinding Method (Object^, String^)

.NET Framework (current version)

Sets the DataSource and DataMember properties at run time.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

Syntax

public:
void SetDataBinding(
	Object^ dataSource,
	String^ dataMember
)

Parameters

dataSource: Type: System::Object^
The data source for the System.Windows.Forms::DataGrid control.

dataMember: Type: System::String^
The DataMember string that specifies the table to bind to within the object returned by the DataSource property.

Exceptions

Exception	Condition
ArgumentException	One or more of the arguments are invalid.
ArgumentNullException	The dataSource argument is null.

Remarks

You must use the SetDataBinding method at run time to reset the DataSource property.

See the DataSource property for more details about setting a valid data source.

You can create a grid that enables users to edit data but prevents them from adding new rows by using a DataView as the data source and setting the AllowNew property to false. When the DataSource is a DataView or DataTable, set the DataMember to an empty string ("").

Examples

The following code example sets the DataSource and DataMember to a DataSet, and a DataTable in the DataSet, respectively.

C++

private:
   void BindControls()
   {
      // Creates a DataSet named SuppliersProducts.
      DataSet^ SuppliersProducts = gcnew DataSet( "SuppliersProducts" );
      // Adds two DataTable objects, Suppliers and Products.
      SuppliersProducts->Tables->Add( gcnew DataTable( "Suppliers" ) );
      SuppliersProducts->Tables->Add( gcnew DataTable( "Products" ) );
      // Insert code to add DataColumn objects.
      // Insert code to fill tables with columns and data.
      // Binds the DataGrid to the DataSet, displaying the Suppliers table.
      dataGrid1->SetDataBinding( SuppliersProducts, "Suppliers" );
   }
