推荐答案

像这样尝试

Try like this

//Create a DataTable instance
DataTable table = new DataTable();
//Create columns for this DataTable
DataColumn col1 = new DataColumn("ID");
//Define DataType of the Columns
col1.DataType = System.Type.GetType("System.Int");
//Add All These Columns into DataTable table
table.Columns.Add(col1);
//Create a Row in the DataTable table
DataRow row = table.NewRow();
//Fill All Columns with Data
row[col1] = 1;
//Add the Row into DataTable
table.Rows.Add(row);
//Bind this DataTable to a GridView
gvTest.DataSource = table;
gvTest.DataBind();

您需要根据需要进行更改.而在每个Page_Load DataTable上可能会丢失其值.因此，将数据表保留在会话中.
在某个地方看到了确切的要求和样品.您可以在Google上搜索并找到它.

You need to change this as per your needs. while on each Page_Load DataTable might lose its value. So keep the datatable in a session.
Has seen the exact requirement and sample somewhere. You can google it and find it out.
