IRowProvider.RowProviderInit Event

NOTE: This API is now obsolete.

Sends the names and display names of the fields in the provided row.

Namespace:  Microsoft.SharePoint.WebPartPages.Communication
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

[ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartRow instead")]
event RowProviderInitEventHandler RowProviderInit

The event handler receives an argument of type Microsoft.SharePoint.WebPartPages.Communication.RowProviderInitEventArgs containing data related to this event. The RowProviderInitEventArgs properties FieldList and FieldDisplayList provide information specific to this event.

The following code example shows an overridden WebPart.PartCommunicationInit method that creates a RowProviderInitEventArgsobject, sets field names and display names, and then fires the RowProviderInit event. This code example is part of a larger example provided for the IRowProvider interface.

        // Step #7: Override the PartCommunicationInit() method.
        // The PartCommunicationInit method 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. 
        // Some parts may not behave properly if this initialization 
        // information is not received.
        public override void PartCommunicationInit()
        {
            // Ensure that all of the Web Part's controls are created.
            EnsureChildControls();

            // Check if connected.
            if(_connected)
            {
                // If there is a listener, fire the RowProviderInit 
                // event.
                if (RowProviderInit != null)
                {
                    // Create the RowProviderInitEventArgs object for 
                    // the RowProviderInit event.
                    RowProviderInitEventArgs rowProviderInitEventArgs = new RowProviderInitEventArgs();
                    
                    // Set the row field names.
                    rowProviderInitEventArgs.FieldList = _rowFieldNames;

                    // Set the row field display names.
                    rowProviderInitEventArgs.FieldDisplayList = _rowFieldDisplayNames;

                    // Fire the RowProviderInit event.
                    RowProviderInit(this, rowProviderInitEventArgs);
                }
            }
        }
