该怎么办？
我已经创建了数据库连接代码的sql助手文件,并调用该方法,而不是使用sqldatasource进行连接.
The GridView ‘GridView1’ fired event PageIndexChanging which wasn’t
handled.
解决方法
您需要在代码后面声明一个处理PageIndexChanging事件的方法.
类似的东西：
protected void GridView1_PageIndexChanging (object sender,GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
bindGridView(); //bindgridview will get the data source and bind it again
}
private void bindGridView()
{
GridView1.DataSource=getData();
GridView1.DataBind();
}
提供示例代码：
protected void GridView1_PageIndexChanging(object sender,GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
bindGridView(); //bindgridview will get the data source and bind it again
}
protected void Page_Load(object sender,EventArgs e)
{
if(!IsPostBack)
bindGridView();
}
//this is some sample data
private void bindGridView()
{
DataTable t = new DataTable();
t.Columns.Add("Col1");
t.Columns.Add("Col2");
DataRow r = null;
for (int i = 0; i < 25; i++)
{
r = t.NewRow();
r.ItemArray = new object[] { "Val" + i," Another " + i };
t.Rows.Add(r);
}
GridView1.DataSource = t;
GridView1.DataBind();
}
这是标价：
<asp:GridView OnPageIndexChanging="GridView1_PageIndexChanging" AllowPaging="true" PageSize="10" ID="GridView1" runat="server" AutoGenerateColumns="true">
产生这个：
