Question

当用户单击网格上的RegionProjectName字段时，我试图从查询字符串传递网格的RegionProjectID列。我把RegionProjectname作为超链接，下面你也可以找到代码。但这不起作用。请建议我或帮助它为什么不工作。该分页也在我的网格视图中启用。

<asp:GridView ID="ResultGridView" runat="server" AutoGenerateColumns="False" ShowFooter="true"
    DataKeyNames="RegionProjectID" 
    AllowPaging="True" 
    CellPadding="3"

    OnRowDeleting="ResultGridView_RowDeleting" 
    CssClass="mGrid"

        } 

        if (e.CommandName.Equals("AddNew"))
        {

            TextBox txtRegion1 = (TextBox)ResultGridView.FooterRow.FindControl("txtRegion1");
            TextBox txtNatureOFWork1 = (TextBox)ResultGridView.FooterRow.FindControl("txtNatureOFWork1");
            if (txtRegion1.Text != "")
            {
                cmd.Connection = conn;
                cmd.CommandText = "INSERT INTO RegionAndProjectInfo(RegionProjectName, NatureOFWorkID ) Values('" + txtRegion1.Text + "', '" + ddlnatureOfWork.SelectedValue.ToString() + "')";
                conn.Open();
                cmd.ExecuteNonQuery();
            }
            FillVendorGrid();
            conn.Close();
        }
    }

Answer 1

您必须使用

Response.Redirect("Default3.aspx?ID=" + e.CommandArgument.ToString());

而不是服务器传输，导致服务器传输与Response.Redirect相比做了不同的事情。

Server.Transfer方法还有第二个参数 - “preserveForm”。如果将此值设置为True，则使用

等语句

`Server.Transfer("Default3.aspx?ID=" + e.CommandArgument.ToString()`, True);

，现有的查询字符串和任何表单变量仍可供您传输的页面使用。

更多的是文件传输，而不是重定向

Answer 2

<ItemTemplate>
                   <asp:hyperlink id="LinkButton3" navigateurl='<%# "Default3.aspx?ID=" + Eval("RegionProjectID")%>' text='<%# Bind("RegionProjectName")%>' runat="server" />  
                </ItemTemplate>

我已经更新了Regionprojectname的itemtemplate，现在获取了查询字符串。

查询字符串在分页启用的网格视图中不起作用
