如何使用GridView在ListView中动态更改单元格值

Question

I have used the GridView inside the ListView. I want to dynamically change a cell value. For example, there is a column named "Time", I wanna to change this value when something happens. I can find and get the cell (eg od.Time as in following codes), but can not change its value . Some codes like this where ObjectData is the class for all ListView columns.

for (int i = 0; i < 5; i++)
{
      ObjectData od = (ObjectData)objectListView.Items[i];
      if (od.UserName == "Tom")
      {
          od.Time = DateTime.Now.ToString();
      }
 }

If the your listview is bound to a data source you'll need to change the data source's data, not the listview's contents. It should then update the listview.
