asp.net中gridview中的分页问题 [英] a problem with paging in gridview in asp.net

问题描述

嗨所有

i在asp.net中有一个gridview，我启用了allow paging，我为事件编写了代码grdShowNews_PageIndexChanging



when我点击gridview底部的页码我点击后页码是不可见的。

感谢所有

对不起，如果我不能写得很好。



PageIndexChanging代码

protected void grdShowNews_PageIndexChanging（object sender，GridViewPageEventArgs e）

{

试试

{

news.IsCounty = IsCounty;

if（IsCounty）grdShowNews.Columns [2] .Visible = true;

grdShowNews.DataSource = news.ListArchive（）;

grdShowNews.PageIndex = e.NewPageIndex;

grdShowNews.DataBind （）;

if（！IsCounty）grdShowNews.Columns [2] .Visible = false;

}

catch（Exception ex）

{

（（ASP.tools_popup_ascx）Page.Master.FindControl（Popup））。Show（ex.Message，خطا）;

}



}

}

and this is my gridview

        <AlternatingRowStyle CssClass="GridAlternativeRow" />
        <Columns>
            <asp:TemplateField ControlStyle-Width="100" HeaderText="عنوان" ItemStyle-Width="100px">
                <ItemTemplate>
                    <%# TextTools.GetSubStringText(Eval("Title").ToString(),40) %>
                </ItemTemplate>
                <ControlStyle Width="100px" />
                <ItemStyle Width="100px" />
            </asp:TemplateField>
            <asp:TemplateField ControlStyle-Width="200" HeaderText="متن" ItemStyle-Width="200px">
                <ItemTemplate>
                    <%# TextTools.GetSubStringText(Eval("Text").ToString(),100) %>
                </ItemTemplate>
                <ControlStyle Width="200px" />
                <ItemStyle Width="200px" />
            </asp:TemplateField>
            <asp:TemplateField HeaderText="تاریخ">
                <ItemStyle Width="60px" />
                <ItemTemplate>
                    <%#ConvertDate.GetPersianDate((DateTime)Eval("Date")) %>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
        <EditRowStyle Height="80px" />
        <HeaderStyle CssClass="GridHeader" Height="40px" />
        <PagerSettings Mode="NumericFirstLast" />
        <PagerStyle CssClass="pagerStyle" />
        <RowStyle CssClass="GridRowsStyle" Height="60px" />
    </asp:GridView>

推荐答案

您可以在一个函数中写入gridview的绑定并将其称为

Hi write binding of gridview in one function and call it like

Private void BindNews();
{
 //Binding code
}
protected void grdShowNews_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
  grdShowNews.PageIndex = e.NewPageIndex;
  BindNews();
}

在PageIndexChanging事件中，

In PageIndexChanging Event,

grdShowNews.PageIndex = e.NewPageIndex;

//Method to Load your GridView

Bind_Grid();

点击Page Number链接后，您的DataSource

After clicking the Page Number link, your DataSource

news.ListArchive();

会丢失它的数据，所以这样做，





在PageIndexChanging事件中，

will lose its data, so do like this,


In PageIndexChanging Event,

grdShowNews.PageIndex = e.NewPageIndex;

//Method to Load your GridView

Bind_Grid();
