问题描述

我使用datatable（View State）作为数据源来绑定Gridview，但是如何将datatable更新为datasource。

i am using datatable(View State) as datasource to bind Gridview but how to update datatable to datasource.

protected void GridView3_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {

            GridViewRow row = (GridViewRow)GridView3.Rows[e.RowIndex];
            DataTable tableupd = ViewState["CurrentTable"] as DataTable;
            
          //How to Update datatable here.....

            GridView3.DataSource = tableupd;
            GridView3.DataBind();
        
        }

推荐答案

foreach(DataRow dr in table.Rows) // search whole table
    {
        if(dr["Product_id"] == 2) // if id==2
        {
            dr["Product_name"] = "cde"; //change the name
            //break; break or not depending on you
        }
    }
