Question

我正在使用ASP.NET 4和MVC并尝试添加代码来处理“选择”链接。一旦用户选择了行，我需要显示一个包含更多细节的新页面。我试图捕获rowcommand但我从来没有打过断点。这是我当前第一页的GridView代码 -

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<ValidationPortal.Models.Contact>>" %>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <form id="form1" runat="server">

    <h2>Index</h2>

    <p>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            DataKeyNames="Id" DataSourceID="SqlDataSource1">
            <Columns>
                <asp:CommandField ShowSelectButton="True" />
                <asp:BoundField DataField="Id" HeaderText="Id" InsertVisible="False" 
                    ReadOnly="True" SortExpression="Id" />
                <asp:BoundField DataField="FirstName" HeaderText="FirstName" 
                    SortExpression="FirstName" />
                <asp:BoundField DataField="LastName" HeaderText="LastName" 
                    SortExpression="LastName" />
                <asp:BoundField DataField="Phone" HeaderText="Phone" SortExpression="Phone" />
                <asp:BoundField DataField="Email" HeaderText="Email" SortExpression="Email" />
            </Columns>
        </asp:GridView>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
            SelectCommand="SELECT * FROM [Contacts]"></asp:SqlDataSource>

    </p>
    </form>

</asp:Content>

我需要添加什么才能使其正常工作？

Answer 1

我认为您需要在网格标记中指定OnSelectedIndexChanged事件。您的活动可能只是重定向到您的详细信息页面，其中包含所选项目的ID。它看起来像这样：

网格：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    DataKeyNames="Id" DataSourceID="SqlDataSource1"
    OnSelectedIndexChanged="SelectEvent">
        // rest of grid definitions
</asp:GridView>

C＃：

protected void SelectEvent(object sender, EventArgs e)
{
    if (GridView1.SelectedIndex >= 0)
       Response.Redirect("yourpage.aspx?itemid=" + (int)GridView1.SelectedValue);
}

就个人而言，我会跳过select命令并创建一个带有指向您网址链接的项目模板，如图所示here

试试这种方式

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Select")
        {
           // Do something
         }
     }

如果您不想使用row命令或者想要显式触发rowcommand，请使用以下代码段

int GridView1TotalCount = GridView1.Rows.Count;
        int r = Convert.ToInt32(dslno)-1;
        if (r != -1)
        {
            if (GridView1TotalCount > r)
            {

                GridViewRow thisGridView1 = GridView1.Rows[r];
                ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" + thisGvEmpMaster.RowIndex);
               // Do something here you have datakey like
           int dkkey = Convert.ToString(GridView1.DataKeys[thisGridView1.RowIndex].Value);


            }
         }
