在gridview中更改页码时未调用PageIndexChanging函数

Question

亲爱的叠花，

我在前端页面中有一个gridview，这里是ASP.NET代码：

 <asp:GridView ID="grdManufact" runat="server" AutoGenerateColumns="False" 
    BackColor="White" BorderColor="#336666" BorderStyle="Double" BorderWidth="3px" CellPadding="4" 
    GridLines="Horizontal" AllowPaging="True" OnRowDataBound="manufGridView_RowDataBound"                             EnableModelValidation="False" EnableSortingAndPagingCallbacks="True" HorizontalAlign="Center"   OnSelectedIndexChanged="grdManufact_SelectedIndexChanged" OnPageIndexChanging="grdManufact_PageIndexChanging">
  <Columns>
      <asp:BoundField DataField="SrNo" HeaderText="SrNo" />
     <asp:BoundField DataField="Manufacturer" HeaderText="Manufacturer" />
     <asp:BoundField DataField="Description" HeaderText="Description" />
     <asp:BoundField DataField="isModerated" HeaderText="Approved" />
     <asp:BoundField />

protected void grdManufact_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    grdManufact.PageIndex = e.NewPageIndex;
    BindGrid();
}

public void BindGrid()
{
    string strConnectionString =   ConfigurationManager.ConnectionStrings["ConnectionString2"].ToString();
    SqlConnection conn = new SqlConnection(strConnectionString);    // Connect to database
    conn.Open();                                                    // Open Connection
    string com = "select ManufacturerID as SrNo, ManufacturerName as Manufacturer,        ManufacturerDescription as Description,isModerated From VehicleManufacturer";
    SqlDataAdapter adpt = new SqlDataAdapter(com, conn); // Select all manufacturers in the table
    DataTable dt = new DataTable();                                 // Create a new Data Table
    adpt.Fill(dt);                                                  // Fill it with manufacturers
    grdManufact.DataSource = dt;    // Make the datasource of the manufacturer grid the new table
    grdManufact.DataBind();                                         // Bind data for the grid
    conn.Close();                                     // Close database connection. Disconnect
}

你能告诉我我做错了什么吗？或者告诉我正确的方向来解决这个问题吗？

我记得如果您设置enableviewstate=false就会发生这种情况。使其enableviewstate=true！如果网格在每次回发时消失，只需将绑定放在Page_Load方法中的If(!ispostback)中。
