Gridview没有刷新数据 [英] Gridview not refreshing data

问题描述

你好！

我的网站有问题。我在Fancybox中打开一个新页面并添加记录。当我关闭或更新时，gridview返回但是尽管添加了数据表（包含所有记录）和数据绑定，屏幕没有更新记录。

 {
 DataTable dtlineas = f.ObtenerLineasPedidoWeb（Session [   Pedido]。ToString（））;

 gridPedido.DataSource =  null ; 
 gridPedido.DataBind（）; 
 gridPedido.DataSource = dtlineas; 
 gridPedido.DataBind（）; 
 
  if （gridPedido.Rows.Count >   0 ）
 {
 pnl_Pedido.Visible =  true ; 
} 
} 

解决方案

 DataTable dtlineas = f.ObtenerLineasPedidoWeb（Session [ Pedido]的ToString（））; 
 gridPedido.DataSource = dtlineas; 
 gridPedido.DataBind（）; 

单独使用上述代码并通过插入检查dtlineas数据表是否具有更新的记录调试器。

Hello there!
I have a problem with my website. I open a new page in Fancybox and add records. When I close or update, the gridview back but despite adding the datatable (contains all the records) and databind, screen no updates records.

<asp:GridView ID="gridPedido" runat="server" CssClass="miGrid" AutoGenerateColumns="false" DataKeyNames="CodProducto,Variante"

            onrowdeleting="gridPedido_RowDeleting" onrowcommand="gridPedido_RowCommand" OnSelectedIndexChanged="gridPedido_SelectedIndexChanged"  >
                <Columns>
                    <asp:BoundField DataField="Pedido" HeaderText="Pedido" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" ReadOnly="true" />
                    <asp:BoundField DataField="Linea" HeaderText="Linea" ItemStyle-HorizontalAlign="Left" ReadOnly="true" />
                    <asp:BoundField DataField="CodProducto" HeaderText="Tipo Contenedor" />
                    <asp:BoundField DataField="Producto" HeaderText="Tipo" ItemStyle-HorizontalAlign="Left" ReadOnly="true" />
                    <asp:BoundField DataField="Variante" HeaderText="Variante" ItemStyle-HorizontalAlign="Center" ReadOnly="true"  />
                    <asp:BoundField DataField="Servicio" HeaderText="Servicio" ItemStyle-HorizontalAlign="Center" ReadOnly="true" />
                    <asp:CommandField ShowEditButton="false" EditText="Editar" UpdateText="Aceptar"

                    CancelText="Cancelar" DeleteText="Borrar" ButtonType="Image"

                    CancelImageUrl="~/resources/images/cancelar.png" EditImageUrl="~/resources/images/modificar.png"

                        ShowSelectButton="true" SelectText="Seleccionar" SelectImageUrl="~/resources/images/modificar.png"

                    UpdateImageUrl="~/resources/images/aceptar.png" ShowDeleteButton="true"  DeleteImageUrl ="~/resources/images/basura.png"/>
                    <asp:ButtonField Text="Añadir contenido" ImageUrl="~/resources/images/add.png" CommandName="AñadirContenido" ButtonType="Image" />
                </Columns>
                <EmptyDataTemplate>
                <div style="text-align:center">No se han encontrado elementos</div>
                </EmptyDataTemplate>
            </asp:GridView>

protected void ActualizarGrid()
{
    DataTable dtlineas = f.ObtenerLineasPedidoWeb(Session["Pedido"].ToString());
    ViewState["Lineas"] = dtlineas;

    gridPedido.DataSource = null;
    gridPedido.DataBind();
    gridPedido.DataSource = dtlineas;
    gridPedido.DataBind();

    if (gridPedido.Rows.Count > 0)
    {
        pnl_Pedido.Visible = true;
    }
}

解决方案

DataTable dtlineas = f.ObtenerLineasPedidoWeb(Session["Pedido"].ToString());
gridPedido.DataSource = dtlineas;
gridPedido.DataBind();

Use the above codes alone and check whether the dtlineas datatable has the updated records by inserting debugger.
