我在ConsumerList页一个GridView。当点击编辑按钮（每一行中），它​​被导航到一个EditConsumer页。在EditConsumer页面，我需要使用网页。previousPage ，以获得所选行的值。如何获得这些价值？

 公共无效Consumer_RowCommand（对象发件人，GridViewCommandEventArgs E）

        如果（e.CommandName ==CustomEdit）

            字符串consumerUrl = grdConsumers.Rows [rowIndex位置] .Cells [3]。文;
            字符串consumerStatus = grdConsumers.Rows [rowIndex位置] .Cells [4]。文;

            的Response.Redirect（EditConsumer.aspx rowIndex位置=？+ rowIndex位置）;

解决方案

注意： previousPage 仅！= NULL 与跨页投递 ，的Response.Redirect 会不行。因此，例如，你可以使用 的Server.Transfer 。

您可以提供一个公共财产 SelectedConsumer ，返回curerently选定行中的的GridView 自定义对象。

 大众消费者SelectedConsumer
{
    得到 {
        如果（grdConsumers.SelectedRow == NULL）
            返回null;

        变种C =新客户（）;
        c.consumerID = grdConsumers.SelectedRow.Cells [1]。文;
        c.consumerName = grdConsumers.SelectedRow.Cells [2]。文;
        c.consumerUrl = grdConsumers.SelectedRow.Cells [3]。文;
        c.consumerStatus = grdConsumers.SelectedRow.Cells [4]。文;

        返回℃;
    }
}
 

现在，你只需要在 previousPage 属性转换为正确的页面类型：

  VAR consumerList =（ConsumerList）页previousPage。
VAR selectedConsumer = consumerList.SelectedConsumer;
 

I have a gridView in ConsumerList page. When Edit button is clicked (in each row), it is navigated to a EditConsumer page. In the EditConsumer page, I need to get the values of the selected row using Page.PreviousPage. How to get these values?

    public void Consumer_RowCommand(Object sender, GridViewCommandEventArgs e)
    {

        if (e.CommandName == "CustomEdit")
        {
            int rowIndex = Convert.ToInt32(e.CommandArgument);
            string consumerID = grdConsumers.Rows[rowIndex].Cells[1].Text;
            string consumerName = grdConsumers.Rows[rowIndex].Cells[2].Text;
            string consumerUrl = grdConsumers.Rows[rowIndex].Cells[3].Text;
            string consumerStatus = grdConsumers.Rows[rowIndex].Cells[4].Text;

            Response.Redirect("EditConsumer.aspx?RowIndex=" + rowIndex);
        }
    }

  <asp:GridView ID="grdConsumers" runat="server" AutoGenerateColumns="False" CssClass="resultGridTable"
                GridLines="None" EnableViewState="True" AllowSorting="True" OnSorting="Consumers_Sorting" OnRowCommand="Consumer_RowCommand">
                <AlternatingRowStyle BackColor="#E5E5E5" />
                <Columns>

                   <asp:TemplateField HeaderText="Action">

                             <asp:Button ID="btnView" runat="server" CssClass="actionButtonView"
                                  Text="VIEW" Style="width: 40px" BackColor="Orange"
                                  Font-Bold="True" ForeColor="White" /> 

                             <asp:Button ID="btnEdit" runat="server" CommandName="CustomEdit" CommandArgument="<%# ((GridViewRow)Container).RowIndex %>"
                              CssClass="actionButtonEdit"

                                  Font-Bold="True" ForeColor="White" />

                                  Font-Bold="True" ForeColor="White" />

                             <asp:Button ID="btnPing" runat="server" CssClass="actionButtonPing"
                                  Text="PING" Style="width: 35px" BackColor="Orange"
                                  Font-Bold="True" ForeColor="White" />

                         </ItemTemplate>
                    </asp:TemplateField>

                    <asp:BoundField HeaderText="Consumer ID" DataField="ConsumerID" SortExpression="ConsumerID"></asp:BoundField>
                    <asp:BoundField HeaderText="Consumer Name" DataField="ConsumerName" SortExpression="ConsumerName"></asp:BoundField>
                    <asp:BoundField HeaderText="Consumer URL" DataField="ConsumerURL" SortExpression="ConsumerURL"></asp:BoundField>
                    <asp:BoundField HeaderText="Status" DataField="Status" SortExpression="Status"></asp:BoundField>



                </Columns>
            </asp:GridView>

Note: PreviousPage is only != null with cross page posting, Response.Redirect will not work. So you could for example use Server.Transfer.

You could provide a public property SelectedConsumer that returns a custom object of the curerently selected row in the GridView.

public Consumer SelectedConsumer
{
    get {
        if (grdConsumers.SelectedRow == null)
            return null;

        var c = new Consumer();
        c.consumerID = grdConsumers.SelectedRow.Cells[1].Text;
        c.consumerName = grdConsumers.SelectedRow.Cells[2].Text;
        c.consumerUrl = grdConsumers.SelectedRow.Cells[3].Text;
        c.consumerStatus = grdConsumers.SelectedRow.Cells[4].Text;

        return c;
    }
}

Now you only have to cast the PreviousPage property to the correct page type:

var consumerList = (ConsumerList)Page.PreviousPage;
var selectedConsumer = consumerList.SelectedConsumer;
