Question

我有一个FormView，UpdateButton和SqlDataSource位于下方。我的updatebutton总是使用相同的值（我的gridview第一行的值）更新Sil表，我无法弄清楚原因。

<asp:FormView ID="frm_Benefit" runat="server" DataKeyNames="ID" DataSourceID="sds_Benefits"
            OnItemInserted="frm_Benefit_ItemInserted" OnItemUpdated="frm_Benefit_ItemUpdated">
    <EditItemTemplate>
        <table class="formview">
            <tr>
                <td>
                    Code:

                <td>
                    <asp:TextBox ID="CodeTextBox" runat="server" Text='<%# Bind("Code") %>' />
                </td>
            </tr>
            <tr>

RowCommand：

    protected void grd_Benefits_RowCommand(object sender, GridViewCommandEventArgs e)
    {            
        if (e.CommandName == "ViewRecord")
        {
            grd_Benefits.SelectedIndex = int.Parse(e.CommandArgument.ToString());
            frm_Benefit.ChangeMode(FormViewMode.ReadOnly);
            Page.ClientScript.RegisterStartupScript(this.GetType(), "ShowFormViewView", "<script type=\"text/javascript\">showFormViewView();</script>");
        }
        else if (e.CommandName == "NewRecord")
        {
            frm_Benefit.ChangeMode(FormViewMode.Insert);
            Page.ClientScript.RegisterStartupScript(this.GetType(), "ShowFormViewInsert", "<script type=\"text/javascript\">showFormViewInsert();</script>");
        }
        else if (e.CommandName == "EditRecord")
        {
            grd_Benefits.SelectedIndex = int.Parse(e.CommandArgument.ToString());
            frm_Benefit.ChangeMode(FormViewMode.Edit);
            Page.ClientScript.RegisterStartupScript(this.GetType(), "ShowFormViewEdit", "<script type=\"text/javascript\">showFormViewEdit();</script>");
        }
    }

Answer 1

看到你的标记并按原样使用，问题在于FormView。

您尚未为FormView设置AllowPaging =“true”。因此，每次FormView显示时，它只显示检索到的所有数据记录的第一行。

[请注意，表单视图一次只显示一条记录]。

因此，每次在表单视图中选择“编辑”时，您实际上只编辑第一条记录（实际上是GridView的第一行）。

为FormView设置AllowPaging属性为true。

<asp:FormView ID="frm_Benefit" runat="server" DataKeyNames="CustomerID"
 DataSourceID="sds_Benefits" OnItemUpdated="frm_Benefit_ItemUpdated" 
AllowPaging="true">

之后使用分页索引，导航到您要更改的任何记录并进行编辑，如下所示。 enter image description here

SqlDataSource UpdateCommand参数没有变化
