Provides FieldName and FieldDisplayName property values to a Web Part that implements the ICellConsumer interface.

event CellProviderInitEventHandler CellProviderInit

The following code example shows an overridden WebPart.PartCommunicationInitmethod that creates a CellProviderInitEventArgs data structure to contain the FieldName and FieldDisplayName property values, sets the property values, and then fires the CellProviderInit event. This code example is part of a larger example provided for the ICellProvider interface.

        // Step #9: Override the PartCommunicationInit() method
        // PartCommunicationInit() is called by the Web Part 
        // infrastructure during the ASP.Net PreRender 
        // event to allow the part to pass initialization information 
        // to the other connected parts.
        // It is important to always pass initialization information as 
        // some parts may not behave properly if this initialization 
        // information is not received.
        public override void PartCommunicationInit()
            // Check if connected
                // If there is a listener, fire the CellProviderInit 
                // event.
                if (CellProviderInit != null)
                    // Create the InitEventArgs structure for the 
                    // CellProviderInit event.
                    CellProviderInitEventArgs cellProviderInitArgs = 
                       new CellProviderInitEventArgs();
                    // Set the FieldName and FieldDisplay values.
                    cellProviderInitArgs.FieldName = _cellName;
                    cellProviderInitArgs.FieldDisplayName = 
                    // Fire the CellProviderInit event.
                    CellProviderInit(this, cellProviderInitArgs);
