Repeater動態創建刪除行

最近在的一個項目是需要把Repeater進行動態創建行，和刪除行。並且界面上需要進行Checkbox選項的，使用了Repeater實現。方法有些笨。有好的，請大家指教一下。下面貼代碼。

 <asp:Repeater ID="rptUserList" runat="server">
        <HeaderTemplate>
            <table width="100%" border="0" cellpadding="0" cellspacing="0" class="tableadd">
                <tr>
                    <th></th>
                    <th>
                        手機號碼
                    </th>
                    <th>
                        用戶姓名
                    </th>
                    <th>
                        GSM接通率
                    </th>
                    <th>
                        TD接通率
                    </th>
                </tr>
        </HeaderTemplate>
        <ItemTemplate>
            <tr>
                <td>
                <asp:CheckBox ID="chkDel" runat="server" />
                </td>
                <td>
                    <asp:Label ID="Label2" runat="server" Text='<%#Eval("User")%>'></asp:Label>
                </td>
                <td>
                    <asp:TextBox ID="TextBox2" runat="server" Width="100" Text='<%#Eval("User")%>'></asp:TextBox>
                </td>
                <td>
                    <asp:CheckBox ID="CheckBox3" runat="server" Checked='<%#Eval("GSM接通率")%>' />
                    &nbsp;
                </td>
                <td>
                    <asp:CheckBox ID="CheckBox2" runat="server" Checked='<%#Eval("TD接通率")%>' />
                </td>
            </tr>
        </ItemTemplate>
        <FooterTemplate>
            </table>
        </FooterTemplate>
    </asp:Repeater>

-------------------------------------------------------------------------------------------------------------------------

上面是一個界面的ASPX界面。

DataTable ExecuDataTable()
        {
           //需要綁定數據庫，返回一個DataTable類型

      ｝

 

綁定數據。

 if (!IsPostBack)
            {
                DataTable dtData = ExecuDataTable();

                rptUserList.DataSource = dtData;
                rptUserList.DataBind();
            }

-----------------------------------------------------------------------------------------------------------------------------

新增數據的按鈕

 protected void btnAdd_Click(object sender, EventArgs e)
        {
            DataTable dt = ExecuDataTable();
            DataRow dr = dt.NewRow();
            dt.Rows.Add(dr);
            rptUserList.DataSource = dt;
            rptUserList.DataBind();
        }

---------------------------------------------------------------

刪除行時的處理，這個時候實際上是沒有刪除的，只是讓該行沒有顯示，所以在更新到數據庫時需要注意。判斷Item.Visible 的屬性，在最下面會有代碼示例。

protected void btnDel_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < rptUserList.Items.Count; i++)
            {
                CheckBox chkdel = (CheckBox)rptUserList.Items[i].FindControl("chkDel");
                if (chkdel != null)
                {
                    if(chkdel.Checked)
                        rptUserList.Items[i].Visible = false;
                }
               
            }
        }

-------------------------------------------------

下面爲需要更新數據，先找到該控件，再進行轉換處理。

  protected void btnUpdate_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < rptUserList.Items.Count; i++)
            {

               if (rptUserList.Items[i].Visible)
                {
                CheckBox CheckBox3 = (CheckBox)rptUserList.Items[i].FindControl("CheckBox3");
                CheckBox CheckBox2 = (CheckBox)rptUserList.Items[i].FindControl("CheckBox2");
                Label Label2 = (Label)rptUserList.Items[i].FindControl("Label2");
                TextBox TextBox2 = (TextBox)rptUserList.Items[i].FindControl("TextBox2");

                //連接成SQL進行更新

               ｝

             ｝

｝

------------------------------------------------------------

該方案也有一些弊端，比如，當前己經將某列選中，但是，沒有更新到數據時，再添加就會刷新以前的數據。建議有一些提示比較好。
