  Get value of Id not displayed in the Repeater from a button event of a dialog

  Dec 04, 2012 04:14 PM|LINK

  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, but I have it in the DataSet with which I fill it. 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>

  I could have the Id of the Items in the .cs by doing this in the Repeater:

  <div id ="Hield" runat="server" visible="false"> <%# Eval("aux_approvalId")%> </div>

  And in the code behind: 

  foreach (RepeaterItem item in rptActiveChanges.Items)
              {
                  System.Web.UI.HtmlControls.HtmlGenericControl hiddenContent2 = (System.Web.UI.HtmlControls.HtmlGenericControl)item.FindControl("Hield");
                  string ReportID = hiddenContent2.InnerHtml;
              }

  But now, how can I know which row has benn selected?

  You can handle your Repeater ItemCommand event:

  protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
          {
              System.Web.UI.HtmlControls.HtmlGenericControl hiddenContent2 = (System.Web.UI.HtmlControls.HtmlGenericControl)e.Item.FindControl("Hield");
              string ReportID = hiddenContent2.InnerHtml;
          }

  now if you click on the image(that will fire the Repeater ItemCommand event) of Repeater, you will get the ReportID that you selected.

  note: please replace <img> tag with ImageButton in the Repeater.

  Hi Frank, I have this:

  <td class ="approval-img"><asp:ImageButton  class ="declineDialog" runat="server"  CommandArgument = '<%# Eval("aux_approvalId")%>'  OnClick="test_rr"/></td>

  and the repetear:

  <asp:Repeater ID="rptActiveChanges" runat="server" OnItemCommand="Repeater1_ItemCommand" >

  
  
  

  the class declineDialog do that an jQuery dialog opens, so if I write it, any of the two events (Repeater1_ItemCommand and test_rr) are firing.

  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);
