Leaving Words Management

First, let's look at the run-time snapshot for leaving words management (the "leavewordManage.aspx"), as is shown in Figure 38.

It's still easy-merely a GridView control on the page with a few related links embedded in it to perform the viewing and deleting operation.

Initialization and Data Binding

When the "leavewordManage.aspx" page is initialized, the related left words information is bound to the "LeavewordView" GridView so that the words left by customers are displayed within the grid control, as is shown in the following code:

protected void Page_Load(object sender,EventArgs e){

if(!Page.IsPostBack)

{ ///bind data to the control

BindLeavewordData();

}

}

private void BindLeavewordData(){

///define the class that gets the data

Leaveword word = new Leaveword();

SqlDataReader dr = word.GetLeavewords();

///Set the control's data source

LeavewordView.DataSource = dr;

///bind data to the control

LeavewordView.DataBind();

///Close the database connection

dr.Close();

}
