asp.net gridview 分页问题
现在想要实现页面上有一个下拉框,是控制分页的页数,下拉框选择一个分页数目,gridview就按照这个分页数分页。
请问大侠们有什么方法。
public void DataBingGridView() //数据绑定
{
//get time parameters
string date1 = CommonMethod.ConvertToStr(txtBeginDate.Text);
string date2 = CommonMethod.ConvertToStr(txtEndDate.Text);
//get cashflow method and has parameters
DataTable dt = BLL.CashFlow.GetFullCashData(date1, date2).Tables[0];
//DataTable dt = BLL.CashFlow.GetFullCashData().Tables[0];
PagedDataSource pds = new PagedDataSource();
pds.DataSource = dt.DefaultView;
//paging
pds.AllowPaging = true;
pds.PageSize = 25;// 这个是控制分页数目的,就是想让其是动态可以设置的
PageControl1.DataSource = pds;
//bind data
GroupedGridView1.DataSource = pds;
GroupedGridView1.DataBind();
}
请问有什么好的解决方案
[最优解释]
/// <summary>

/// <param name="sender"></param>
/// <param name="e"></param>
protected void GvProduct_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GvProduct.PageIndex = e.NewPageIndex;
_DataBind();
//执行Go
TextBox txtGoPageNum = (TextBox)GvProduct.BottomPagerRow.FindControl("txtGoPageNum");
txtGoPageNum.Text = (GvProduct.PageIndex + 1).ToString();
}

if (e.CommandName == "Go")
{
try
{
TextBox txtGoPageNum = (TextBox)GvProduct.BottomPagerRow.FindControl("txtGoPageNum");//底部导航命令
int newPageIndex = Int32.Parse(txtGoPageNum.Text.Trim());
GridViewPageEventArgs gvpe = new GridViewPageEventArgs(newPageIndex - 1);
GvProduct_PageIndexChanging(null, gvpe);//重新分页
}
catch { }
}
}
<PagerTemplate>
<br />

转到第<asp:TextBox runat="server" ID="txtGoPageNum" Width="30px"></asp:TextBox>页
<asp:Button ID="btnGo" CommandName="Go" runat="server" Text="Go" />
