我有一个包含10000条记录的表,因此我只想使用存储过程一次只调用15条记录。
在下次通话时,仅拨打下15个Reocord,然后继续...
请帮帮我!! ...如果可能,请提供示例代码和存储过程代码...谢谢!!!

在gridview中使用分页作为AllowPaging =“ true”,然后使用 OnPageIndexChanging事件并为我们提供PageSize,请参见以下示例
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowPaging="true"
OnPageIndexChanging="OnPageIndexChanging" PageSize="10">
<Columns>
<asp:BoundField ItemStyle-Width="150px" DataField="Column_Name" HeaderText="Header Name" />
<asp:BoundField ItemStyle-Width="150px" DataField="Column_Name" HeaderText="Header Name" />
<asp:BoundField ItemStyle-Width="150px" DataField="Column_Name" HeaderText="Header Name" />
</Columns>
</asp:GridView>
现在在Page_Load事件上将gridview与数据库绑定
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}
}
private void BindGrid()
{
string conStr = @"Your connection string here";
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand("SELECT * FROM Table_Name"))
{
using (SqlDataAdapter sda = new SqlDataAdapter())
{
cmd.Connection = con;
sda.SelectCommand = cmd;
using (DataTable dt = new DataTable())
{
sda.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
}
}
}
}
}
对于页面,请在OnPageIndexChanging事件上使用newPageIndex
protected void OnPageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
BindGrid();
}
