Question

我有一个用于更新记录的FormView。有一个链接按钮，当发生火灾时，应通过BLL和DAL进行更新。我没有使用内置的ODS，我也不会考虑使用它。

我通过调用从数据库中获取数据的方法，手动填充了所有网格和表单。

例如，我的详细信息视图填充如下：

protected void DlMembers_ItemCommand(object source, DataListCommandEventArgs e)
{
    if (e.CommandName.ToString() == "Select")
    {
        DlMembers.Visible = false;
        lblError.Text = string.Empty;
        lblError.Visible = false;
        fvMemberDetail.Visible = true;
        fvMemberDetail.ChangeMode(FormViewMode.Edit);

        MemberBLL getMemberInfo = new MemberBLL();

        int Ident = Convert.ToInt32(e.CommandArgument.ToString());

        fvMemberDetail.DataSource = getMemberInfo.GetMemberByIdent(Ident);
        fvMemberDetail.DataBind();

    }

    if (e.CommandName.ToString() == "DeleteSelected")
    {
        DlMembers.Visible = true;
        lblError.Text = string.Empty;
        lblError.Visible = false;
        fvMemberDetail.Visible = false;
        fvMemberDetail.ChangeMode(FormViewMode.ReadOnly);
  }

如果要在click事件上设置我的链接按钮并执行此操作（除了运行时永远不会达到此方法），我想做什么：

protected void MemberInfoUpdating(object sender, EventArgs e)
{
    TextBox id = (TextBox)fvMemberDetail.FindControl("txtIdent");

    if (id.Text != string.Empty || id.Text != "")
    {
        TextBox txtFN = (TextBox)fvMemberDetail.FindControl("txtFN");
        TextBox txtLN = (TextBox)fvMemberDetail.FindControl("txtLN");
        DropDownList ddlAddress = (DropDownList)fvMemberDetail.FindControl("ddlAddress");
        TextBox txtEmail = (TextBox)fvMemberDetail.FindControl("txtEmail");
        TextBox txtHPhone = (TextBox)fvMemberDetail.FindControl("txtHPhone");
        TextBox txtWPhone = (TextBox)fvMemberDetail.FindControl("txtWPhone");
        TextBox txtMPhone = (TextBox)fvMemberDetail.FindControl("txtMPhone");
        DropDownList ddlPos = (DropDownList)fvMemberDetail.FindControl("ddlPos");
        DropDownList ddlIsAdmin = (DropDownList)fvMemberDetail.FindControl("ddlIsAdmin");
        bool blIsAdmin = false;
        if (ddlIsAdmin.SelectedValue == "True") blIsAdmin = true;
        TextBox txtComments = (TextBox)fvMemberDetail.FindControl("txtComments");

        MemberBLL updateMemberInfo = new MemberBLL();

        bool UpdateOK = updateMemberInfo.UpdateMemberByIdent(
                        txtFN.Text,
                        txtLN.Text,
                        ddlAddress.SelectedValue,
                        txtEmail.Text,
                        txtHPhone.Text,
                        txtWPhone.Text,
                        txtMPhone.Text,
                        blIsAdmin,
                        txtComments.Text,
                        Convert.ToInt32(ddlPos.SelectedValue),
                        Convert.ToInt32(id.Text));
    }
    else
    {
        //Display error - no user id cannot update record
    }
}

linkbutton看起来像这样：

<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True" 
                OnClick="MemberInfoUpdating" Text="Update" />

这个LinkButton在哪里？如果它在FormView模板中，那么您可能需要使用类似的东西：

<asp:LinkButton ID="UpdateButton" runat="server" CommandName="Update" Text="Update" />

然后在DlMembers_ItemCommand中处理“更新”命令。

或者，将代码附加到FormView的OnItemUpdating事件而不是一些您不需要的额外事件：

<asp:FormView ID="fvMemberDetail" runat="server" OnItemUpdating="MemberInfoUpdating">

FormView手动数据绑定
