Question

我正在开展一个项目，我很难接受它。我需要在明天完成它，所以我需要你的帮助。问题是我有一个网站有一个叫做编辑的按钮。用户必须单击按钮向他显示两个按钮，一个名为Save，另一个按钮取消，网页上还有另一个名为Submit Hours to chair的按钮。用户必须先输入小时并保存，然后按“提交”按钮。如果用户没有保存并按下“提交”按钮，则弹出消息告诉他需要先放入小时并先保存。这是代码

此代码适用于SUbmit按钮

<asp:Button ID="ButtonSubmitChair" runat="server" Text="Submit Schedule to Chair" SkinID="AspButton" onclick="ButtonSubmitChair_Click"/>

protected void ButtonSubmitChair_Click（object sender，EventArgs e） { objMs.UpdateStatus（“SC”，Convert.ToInt32（Session [“FacId”]），Convert.ToInt32（Session [“TermId”]））; DetailsViewMainSchedule.DataBind（）; GvTeachingSchedule.DataBind（）; GvResearchSchedule.DataBind（）; OfficeHoursGridView.DataBind（）; GridViewOffCampus.DataBind（）; UpdatePanel1.Update（）; UpdatePaneloffcamp.Update（）; UpdatePanel3.Update（）; //ButtonSubmitChair.Enabled = GetSubmitButtonStatus（）; ButtonSubmitChair.Enabled = false; // RZL添加到禁用按钮

        string facmail = "";
        string facname = "";

        DataTable dt1 = objF.GetFacultyEmailId(Convert.ToInt32(Session["FacId"]));
        if (dt1.Rows.Count > 0)
        {
            facmail = dt1.Rows[0]["Email"].ToString();
            facname = dt1.Rows[0]["name"].ToString();

        }
        DataTable dt = objF.GetChairEmail(Convert.ToInt32(Session["DeptID"]));
        string chairname = "";
        string chairmail = "";

        if (dt.Rows.Count > 0)
        {

            chairname = dt.Rows[0]["name"].ToString();
            chairmail = dt.Rows[0]["Email"].ToString();
        }
        string FacultyComments = ((TextBox)(DetailsViewMainSchedule.FindControl("TextBoxFCItem"))).Text;
        string ChairComments = ((TextBox)(DetailsViewMainSchedule.FindControl("TextBoxCCItem"))).Text;
        string DeanComments = ((TextBox)(DetailsViewMainSchedule.FindControl("TextBoxDCItem"))).Text;
        if (FacultyComments == "")
            FacultyComments = "No Comments";
        if (ChairComments == "")
            ChairComments = "No Comments";
        if (DeanComments == "")
            DeanComments = "No Comments";

        try
        {
            objM.message(facname, chairname, FacultyComments, ChairComments, DeanComments, chairmail, facmail, "sc");
        }
        catch (Exception ex)
        {
            Response.Redirect("schedule.aspx?" + pageQueryString);
        }

}`

这是编辑 ASPX <asp:TemplateField ShowHeader="False"> <ItemTemplate> <asp:LinkButton ID="LinkButtonEdit" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" Visible="<%# GetEditStatus() %>"></asp:LinkButton></ItemTemplate><EditItemTemplate> <asp:LinkButton ID="LinkButtonSave" runat="server" CausesValidation="True" CommandName="Update" Text="Save"></asp:LinkButton> <asp:LinkButton ID="LinkButtonCancel" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel"></asp:LinkButton></EditItemTemplate><InsertItemTemplate> <asp:LinkButton ID="LinkButtonInsert" runat="server" CausesValidation="True" CommandName="Insert" Text="Insert" onclick="LinkButtonInsert_Click"></asp:LinkButton> <asp:LinkButton ID="LinkButtoncancel" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel"></asp:LinkButton></InsertItemTemplate></asp:TemplateField> 在这里输入代码

Answer 2

如何设置Session var之类的会话（“isSaved”）= true

当用户点击“保存”时。 “提交”按钮看起来像

if not Session("isSaved")= true then 
    modalForm.Show
else
    'DoSubmit
end if

当我在aspx中启用特定按钮时按下按钮时，我需要显示一条弹出消息
