Gridview在PageIndexChanging上无法正常工作 [英] Gridview not working properly on PageIndexChanging

问题描述

我的前端代码：

My frontend code:

<asp:GridView ID="Gen_Lic_Grid" runat="server" AllowPaging="True" AutoGenerateColumns="False" CellPadding="4" DataKeyNames="Lic_No" ForeColor="#333333" GridLines="None" OnPageIndexChanging="gridView_PageIndexChanging" PageSize="15" Width="110%">
   <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
    <Columns>
 <asp:BoundField DataField="Lic_No" HeaderText="License No" ReadOnly="True" SortExpression="Lic_No" />
 <asp:BoundField DataField="UserID" HeaderText="User ID" SortExpression="UserID" />
 <asp:BoundField DataField="Org" HeaderText="Organization"

                                    SortExpression="Org" />
 <asp:BoundField DataField="UserName" HeaderText="User Name" SortExpression="UserName" />
 <asp:BoundField DataField="SolType" HeaderText="Solution Type" SortExpression="SolType" />
<asp:BoundField DataField="Version" HeaderText="Version" SortExpression="Version" />
<asp:BoundField DataField="Lic_Type" HeaderText="License Type" SortExpression="Lic_Type" />
<asp:BoundField DataField="Meap_Supp" HeaderText="Meap Support" SortExpression="Meap_Supp" />
<asp:BoundField DataField="Lic_From" HeaderText="License From" SortExpression="Lic_From" />
<asp:BoundField DataField="Lic_To" HeaderText="License To" SortExpression="Lic_To" />
<asp:BoundField DataField="Supp_From" HeaderText="Support From" SortExpression="Supp_From" />
<asp:BoundField DataField="Supp_To" HeaderText="Support To" SortExpression="Supp_To" />
<asp:BoundField DataField="Max_User" HeaderText="Max Users" SortExpression="Max_User" />
<asp:BoundField DataField="Max_Mach" HeaderText="Max Machines" SortExpression="Max_Mach" />
<asp:BoundField DataField="Mach_IP" HeaderText="Machine IP" SortExpression="Mach_IP" />
<asp:BoundField DataField="Mach_MAC" HeaderText="Machine MAC" SortExpression="Mach_MAC" />
</Columns>
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<EditRowStyle BackColor="#999999" />
<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
</asp:GridView>

我的后端代码：

My backend code:

protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    Gen_Lic_Grid.PageIndex = e.NewPageIndex;
    Gen_Lic_Grid.DataSource = //<-- what should be written here?
    Gen_Lic_Grid.DataBind();
}

我的gridview在页面更改时是空白的，我没有得到在数据源中写入的内容。有人可以指导我吗？

My gridview is blank on page changing and i''m not getting what to write in the datasource. Can someone guide me?

推荐答案

DataSet ds = new DataSet（）;其中包含数据库数据

Hi,

DataSet ds = new DataSet(); which contain database data

protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    Gen_Lic_Grid.PageIndex = e.NewPageIndex;
//add dataset
    Gen_Lic_Grid.DataSource =ds;
    Gen_Lic_Grid.DataBind();
}

Gen_Lic_Grid.PageIndex = e.NewPageIndex;

//write here the code for filling the datatable or what you have written to fill your gridview
   Gen_Lic_Grid.DataSource = dt
   Gen_Lic_Grid.DataBind();

谢谢

Thanks

您好，



请在加载page_load事件的Gen_Lic_Grid期间将数据表添加到会话中，然后使用它如下所示：

Hello,

please add datatable into session during Gen_Lic_Grid loading on page_load event and then use it as below :

protected void Gen_Lic_Grid_PageIndexChanging(object sender, GridViewPageEventArgs e)
       {
          Gen_Lic_Grid.PageIndex = e.NewPageIndex; 
          Gen_Lic_Grid.DataSource = Session["LicList"];         
          Gen_Lic_Grid.DataBind();

       }
