    How to subscribe to the events of each cell
    In This Topic

    The best way to subscribe to the events of each cell in the grid is to subscribe to the events of each cell in the DataRowTemplate. 

    If your grid is data bound, in order to subscribe to the events of each cell in the DataRowTemplate, you will need to bind the grid between calls to the grid's BeginInit and EndInit methods. 

    If you are providing data manually (unbound mode), then the columns need to be added to the grid before subscribing to the events of each cell in the DataRowTemplate. Once you have subscribed to the events, you can then add your data.

    Demonstration

    The following example demonstrates how to subscribe to the events of each cell in a data bound grid.

    VB.NET Copy Code

    GridControl1.BeginInit() 

    GridControl1.DataSource = DataSet11
    GridControl1.DataMember = "Orders" 

    Dim cell As DataCell
    For Each cell In GridControl1.DataRowTemplate.Cells
      AddHandler cell.Click, AddressOf Me.cell_Click
    Next cell 

    GridControl1.EndInit()

    C# Copy Code

    gridControl1.BeginInit(); 

    gridControl1.DataSource = dataSet11;
    gridControl1.DataMember = "Orders"; 

    foreach( DataCell cell in gridControl1.DataRowTemplate.Cells )
    {
      cell.Click += new EventHandler( this.cell_Click );
    } 

    gridControl1.EndInit();

    For more information on how to use the BeginInit and EndInit methods, jump to the Batch Modifications topic.

    The next example demonstrates how to subscribe to the events of each cell in an unbound grid.

    VB.NET Copy Code

    GridControl1.Columns.Add( New Column( "first" ) )
    GridControl1.Columns.Add( New Column( "second" ) )
    GridControl1.Columns.Add( New Column( "third" ) )
    GridControl1.Columns.Add( New Column( "fourth" ) ) 

    Dim cell As DataCell
    For Each cell In GridControl1.DataRowTemplate.Cells
      AddHandler cell.Click, AddressOf Me.cell_Click
    Next cell 

    AddHandler GridControl1.AddingDataRow, AddressOf Me.AddingRows 

    Dim i As Integer 

    For i = 0 To 20
      GridControl1.DataRows.AddNew().EndEdit()
    Next i

    C# Copy Code

    gridControl1.Columns.Add( new Column( "first" ) );
    gridControl1.Columns.Add( new Column( "second" ) );
    gridControl1.Columns.Add( new Column( "third" ) );
    gridControl1.Columns.Add( new Column( "fourth" ) ); 

    foreach( DataCell cell in gridControl1.DataRowTemplate.Cells )
    {
      cell.Click += new EventHandler( this.cell_Click );
    } 

    gridControl1.AddingDataRow += new AddingDataRowEventHandler( this.AddingRows ); 

    for( int i = 0; i < 20; i++ )
    {
      gridControl1.DataRows.AddNew().EndEdit();
    }
