问题描述

我已经将GridView与数据源连接了.它工作正常，但仅在表单加载时显示.我想在用户单击按钮时显示它.怎么做呢?

谢谢

Hi,
I have connected GridView with a datasource. It works fine but it is displayed just at form load. I want to show it when user clicks the button. How to make it so?

Thanks

推荐答案

请提供任何代码示例?

protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {
            Bind();
        }
    }
private void Bind()
{
  string connectionString =    
  WebConfigurationManager.ConnectionStrings["Northwind"].ConnectionString;
  string selectSQL ="SELECT ProductID, ProductName, UnitPrice FROM Products";
            SqlConnection con = new SqlConnection(connectionString);
            SqlCommand cmd = new SqlCommand(selectSQL, con);
            SqlDataAdapter adapter = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();

            adapter.Fill(ds, "Products");

            GridView1.DataSource = ds;
            GridView1.DataBind();

}
//I want to show it when user clicks the button
private void Button1_click(Object sender,EventArgs e)
{
    Bind();
}

因此，您有任何检查IsPostBack吗?单击按钮绑定数据.

So, do you have any check for IsPostBack ? Bind the Data on Click of Button.
