Question

我是视觉工作室的新手。我有一个Sharepoint列表，其中包含以下字段组名称，用户，部分和活动（这是一个复选框）。我有一个网格视图可视化Web部件，它将从列表中检索值，我需要在网格视图中选中一个复选框。

当用户选中网格视图中的复选框并单击“确定”按钮时，我希望SharePoint列表项“活动”更新为“真”或“是”并取消选中并单击“确定”为“否”或“否”。

以下是我到目前为止所做的工作。我能够从列表中检索值。但是，当我单击复选框时，我的SharePoint列表中没有任何更新。

Answer 1

    uncomment the following lines 
     1. uncomment the following lines
     2. //   dataRow["Active"] = oSplistItem["Active"].ToString();
     3.  in your button_click event, get the row id
     4.  give the id to the splistitem and it will find the items as well as improve performance
     5.  you have to use the AllowUnsafeUpdates before and after your changes

     let me know if I can help further

gridview中的复选框应更新splistitem复选框
