Question

假设我从数据库中检索了一个DataSet。之后我想在ASP.Net C＃的ListView / GridView上显示。我怎样才能做到这一点？我的样品是什么？

Answer 1

试试这个

if(datasetObject.tables.count > 0)
    {
    GridView.DataSource = datasetObject;
    GridView.DataBind();

    }
else
{
  lable.Text = "No Record Found";
}

Answer 2

使用GridView的DataBind()方法执行此操作。像

GridView.DataSource = ds;
GridView.DataBind();

Answer 3

将数据集设置为网格的DataSource属性值，然后调用DataBind（）方法。

void Page_Load(Object sender, EventArgs e)
{
// This example uses Microsoft SQL Server and connects
// to the Northwind sample database. The data source needs
// to be bound to the GridView control only when the 
// page is first loaded. Thereafter, the values are
// stored in view state.                      
if(!IsPostBack)
{

  // Declare the query string.
  String queryString = 
    "Select [CustomerID], [CompanyName], [Address], [City], [PostalCode], [Country] From [Customers]";

  // Run the query and bind the resulting DataSet
  // to the GridView control.
  DataSet ds = GetData(queryString);
  if (ds.Tables.Count > 0)
  {
    AuthorsGridView.DataSource = ds;
    AuthorsGridView.DataBind();
  }
  else
  {
    Message.Text = "Unable to connect to the database.";
  }

}   
}

假设AuthorsGridView是你的GridView控件的ID，GetData方法返回一个包含数据的数据集。
