示例
下面的代码示例演示重写的WebPart.PartCommunicationMain方法创建一个RowReadyEventArgs对象，设置行值和所选内容的状态，然后将触发RowReady事件。此代码示例是示例的一个更大提供的IRowProvider接口的一部分。
// Step #8: Override the PartCommunicationMain method.
// The PartCommunicationMain method is called by the Web Part
// infrastructure on the client during the
// ASP.NET PreRender event to allow the part to pass its
// primary data to the other connected parts.
// It is important to always fire the RowReady event. Some
// parts may not behave properly if they are left waiting for
// this information.
public override void PartCommunicationMain()
{
// Check if connected
if(_connected)
{
//If there is a listener, fire the RowReady event.
if (RowReady != null)
{
// Create the RowReadyEventArgs object for the
// RowReady event.
RowReadyEventArgs rowReadyEventArgs = new RowReadyEventArgs();
// Declare data Variables.
string selectionStatus = "";
DataRow[] dr = new DataRow[1];
// If a row is selected, send the row.
if ( _dataGrid.SelectedIndex > -1)
{
// Generate an array containing the selected
// DataRow(s).
dr[0] = ((DataTable)_dataGrid.DataSource).Rows[_dataGrid.SelectedIndex];
// Set the selection status.
selectionStatus = "Standard";
}
else
{
// The user hasn't selected a row so send null.
dr[0] = null;
// Set selection status.
selectionStatus = "None";
}
// Set Values
rowReadyEventArgs.Rows = dr;
rowReadyEventArgs.SelectionStatus = selectionStatus;
// Fire the RowReady event.
RowReady(this, rowReadyEventArgs);
}
}
}
