CellProviderInitEventArgs 类

请注意:此 API 现在已过时。

包含已初始化时ICellProvider Web 部件创建连接,并将触发ICellConsumer接口CellConsumerInit事件的数据结构。不能继承。

继承层次结构

System.Object
  System.EventArgs
    Microsoft.SharePoint.WebPartPages.Communication.InitEventArgs
      Microsoft.SharePoint.WebPartPages.Communication.CellProviderInitEventArgs

命名空间:  Microsoft.SharePoint.WebPartPages.Communication
程序集:  Microsoft.SharePoint(位于 Microsoft.SharePoint.dll 中)

语法

声明
<ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartField instead")> _
Public NotInheritable Class CellProviderInitEventArgs _
    Inherits InitEventArgs
用法
Dim instance As CellProviderInitEventArgs
[ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartField instead")]
public sealed class CellProviderInitEventArgs : InitEventArgs

示例

下面的代码示例显示创建CellProviderInitEventArgs数据结构,以包含FieldName和FieldDisplayName属性值重写的PartCommunicationInit方法,将设置属性值,然后将触发CellProviderInit事件。此代码示例是示例的一个更大提供的ICellProvider接口的一部分。

      ' 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 Overrides Sub PartCommunicationInit()
         ' Check if connected
         If _connected Then
               ' Create the InitEventArgs structure for the CellProviderInit event.
               Dim cellProviderInitArgs As New CellProviderInitEventArgs()
               
               ' Set the FieldName and FieldDisplay values.
               cellProviderInitArgs.FieldName = _cellName
               cellProviderInitArgs.FieldDisplayName = _cellDisplayName
               
               ' Fire the CellProviderInit event.
               RaiseEvent CellProviderInit(Me, cellProviderInitArgs)
         End If
      End Sub
        // Step #9: Override the PartCommunicationInit() method
        // PartCommunicationInit() is called by the Web Part

        // 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(_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 = _cellDisplayName;
                    
                    // Fire the CellProviderInit event.
                    CellProviderInit(this, cellProviderInitArgs);
                }
            }
        }
