Question

我坐在桌上,有一个顿。这种方法第一次被称作是页数,它完全运作。当我向纽斯排队报到时,这一方法被叫去时,我能够看到该行的脱节。本表的增额,但在浏览器中,没有出现新情况(因此,可能出现一行的情况)。我在“我问答”中使用一个更新小组,但我有同样的影响。我也尝试在这种方法中逐次重提这个表格,但只有一行是SHOWN/RENDERED,但如果我把一些东西放在一行,然后添加另一个字,第一行的脚步就消失了,则可能增加一行,而前一行则删除? Maybe 我必须利用这一看法? 谁能指导我正确解决办法?

private void AddSlot()
        {
            DropDownList ddlProfiles = new DropDownList();
            ddlProfiles.DataSource = DLProfiles.Instance.GetAllProfilesByGid(Int32.Parse(Session["gid"].ToString()));
            ddlProfiles.DataTextField = "pName";
            ddlProfiles.DataBind();

            TableRow row = new TableRow();

            TableCell cellProfile = new TableCell();
            cellProfile.Controls.Add(ddlProfiles);

            TableCell cellStart = new TableCell();
            TextBox startTime = new TextBox();
            cellStart.Controls.Add(startTime);

            TableCell cellEnd = new TableCell();
            TextBox endTime = new TextBox();
            cellEnd.Controls.Add(endTime);

            row.Cells.Add(cellProfile);
            row.Cells.Add(cellStart);
            row.Cells.Add(cellEnd);

            scheduleTable.Rows.Add(row);

        }

<asp:UpdatePanel ID="pnlSchedTable" runat="server">
                <ContentTemplate>
        <div id="divCurrentSchedule" runat="server">
            <h3 id="scheduleTitle" runat="server">
            </h3>

                    <asp:Table ID="scheduleTable" runat="server">
                        <asp:TableHeaderRow ID="rowHeaders" runat="server">
                            <asp:TableHeaderCell Text="Profile Name" />
                            <asp:TableHeaderCell Text="Start time" />
                            <asp:TableHeaderCell Text="End time" />
                        </asp:TableHeaderRow>
                    </asp:Table>
                    <asp:Button ID="btnNewSlot" runat="server" OnClick="btnNewSlot_Click" Text="New Slot" />

        </div></ContentTemplate>
            </asp:UpdatePanel>

When are you calling AddSlot? Chances are, if you want it to run after any page request, whether it be an initial load or a button click, you should move it to Pre-Render ...then your timing issues will be adjusted.
