获取Id的价值不是从一个对话框按钮事件显示在直放站 [英] Get value of Id not displayed in the Repeater from a button event of a dialog

问题描述

我有一个问题，试图让已在点击一个asp.net的中继器ID项的值。我直放站有打开一个对话框的图像，并从该对话框中打开，当我点击批准，我想在cs文件获取此值时，我重定向因为ApproveChange_Click事件。我没有做任何的DataBinder.Eval我想要在直放站检索标识。我怎样才能做到呢？如果我使用会话变量，在那里我可以设置在.aspx页以及如何价值。在此先感谢！

这是直放站：

 ＆LT; TR类=＆LT;％＃Container.ItemIndex％2 = 0！？：奇％GT;＆GT;
     ＆LT; TD类=审批-IMG＆GT;＆LT;一类=approvalDialog的href ='＃'＆GT;＆LT; IMG SRC =/图像/ Approve.pngALT =批准/＆GT;＆LT; / TD＆GT;＆下; / A＆GT;
     ＆LT; TD类=审批-IMG＆GT;＆LT;一类=declineDialog的href ='＃'＆GT;＆LT; IMG SRC =/图像/ Decline.pngALT =拒绝/＆GT;＆LT; / TD＆GT;＆下; / A＆GT;
     ...
＆LT; / TR＆GT;
 

和这个对话框：

 ＆LT; D​​IV ID =审批型的风格=显示：无;光标：默认的＆GT;
    ＆LT; D​​IV CLASS =批准变更＆GT;
        ＆LT; UL＆GT;
        ＆LT;立GT;
            ＆LT; P＆GT;＆LT;标签＆gt;原因及LT; /标签＆gt;＆LT; / P＆GT;
            ＆LT; textarea的ID =txtReason=服务器COLS =1行=1级=必需＆GT;＆LT; / textarea的＆GT;＆LT; BR /＆GT;
        ＆LT; /李＆GT;
        ＆LT;立GT;
            ＆LT;跨度＆GT;
            ＆LT; ASP：按钮的ID =btnApprove=服务器的CssClass =蓝色文本=批准工具提示=批准的OnClick =ApproveChange_Click/＆GT;
            ＆LT;按钮ID =btnCancelApprove级=蓝＆GT;取消＆LT; /按钮＆GT;
            ＆LT; / SPAN＆GT;
        ＆LT; /李＆GT;
        ＆LT; / UL＆GT;
    ＆LT; / DIV＆GT;
＆LT; / DIV＆GT;
 

解决方案

下面是我找到了解决办法：
第一：在中继器的ImageButton改变标记，必须发送一个命令参数事件的几率

 ＆LT; TD类=审批-IMG＆GT;＆LT; ASP：ImageButton的=服务器CommandArgument ='＆LT;％＃的eval（aux_approvalId）％＆GT; 的OnClick =getApprovalID_approve工具提示=批准的ImageUrl =/图像/ Approve.png/＆GT;＆LT; / TD＆GT;
 

所以，当我重定向到OnClick事件，有了这个，我得到的ID，并打开对话框后。

 的ImageButton BTN =（的ImageButton）（寄件人）;
会话[ApprovalID] = btn.CommandArgument;
字符串脚本=OpenApprovalDialog（）;;
Page.ClientScript.RegisterStartupScript（typeof运算（页），，剧本，真）;
 

I'm having a problem trying to get the value of the ID item that has been clicked in an asp.net Repeater. My Repeater has an image that opens a dialog, and from that dialog opened, when I click Approve, I would like to get this value in the .cs file when I'm redirected because the ApproveChange_Click event. I'm not doing any DataBinder.Eval to the Id I want to retrieve in the Repeater. How can I accomplish that? If I use session variables, where I can set up the value in the .aspx page and how. Thanks in advance!

This is the Repeater:

<tr class="<%# Container.ItemIndex % 2 != 0 ? "" : "odd" %>">
     <td class ="approval-img"><a class ="approvalDialog" href='#'><img src="/Images/Approve.png" alt ="Approve"/></td></a>
     <td class ="approval-img"><a class ="declineDialog" href='#'><img src="/Images/Decline.png" alt ="Decline"/></td></a>
     ...
</tr>

And this the dialog:

<div id="approval-form" style="display: none; cursor: default">
    <div class="approve-change">
        <ul>
        <li>
            <p><label>Reason</label></p>
            <textarea id="txtReason" runat="server" cols="1" rows="1" class="required"></textarea><br />
        </li>
        <li>
            <span>
            <asp:Button ID="btnApprove" runat="server" CssClass="blue" Text="Approve" ToolTip = "Approve" OnClick="ApproveChange_Click" />
            <button id="btnCancelApprove" class="blue">Cancel</button>
            </span>
        </li>
        </ul>
    </div>
</div>

解决方案

Here is the solution that I have found: First: change the tag in the repeater for ImageButton, for have the chance to send a command argument to the event

<td class ="approval-img"><asp:ImageButton runat="server" CommandArgument = '<%# Eval("aux_approvalId")%>'  OnClick="getApprovalID_approve" ToolTip="Approve" ImageUrl="/Images/Approve.png" /></td>

So, when I'm redirected to OnClick event, with this, I get the ID and after the dialog is opened.

ImageButton btn = (ImageButton)(sender);
Session["ApprovalID"] = btn.CommandArgument;
string script = "OpenApprovalDialog();";
Page.ClientScript.RegisterStartupScript(typeof(Page), "", script, true);
