  Accessing Repeater Item on Button Click

  Jan 22, 2010 06:20 AM|LINK

  Hi all,

  I stuck in a situation and need some help. I've adde a WebUserControl inside Repeater control. My WebUserControl consists of basically three controls: a CheckBox, a HyperLink, and some Label control. Plz have a look:

  <asp:Repeater ID="Repeater1" runat="server"
                              onitemdatabound="Repeater1_ItemDataBound">
      <HeaderTemplate>
           <table cellpadding="0" cellspacing="0" border="0" width="580">
               <tr>
                   <td width="55%" align="left">
                       <span class="report_heading">Name</span>
                   </td>
                       <td width="15%" align="left">
                           <span class="report_heading">No. of Views</span>
                       </td>
                       <td width="15%" align="left">
                           <span class="report_heading">Ranking</span>
                       </td>
                       <td width="15%" align="left">
                           <span class="report_heading">Relesed Date</span>
                       </td>
                   </tr>
                   <tr>
                       <td colspan="4" width="100%" style="background:url(images/skinny_dots.gif) repeat-x center;">
                               
                       </td>
                   </tr>
               </table>
               <table cellpadding="0" cellspacing="0" border="0" width="580" class="report">
           </HeaderTemplate>
           <ItemTemplate>
               <tr style="background:#faf7f7;">
         	         <td>
         	             <uc1:animation ID="animation1" runat="server" />
         	         </td>
               </tr>
           </ItemTemplate>
           <AlternatingItemTemplate>
               <tr style="background:#fcefef;">
         	         <td>
         	             <uc1:animation ID="animation2" runat="server" />
         	         </td>
               </tr>
           </AlternatingItemTemplate>
           <FooterTemplate>
               </table>
           </FooterTemplate>
       </asp:Repeater>

  I've some Buttons outside the Repeater control. Now I want to select individual row through CheckBox and process it on Button (outside Repeater) Click.

  Plz help me.

  Thanx in advance.
   

  Hope it'll help you..

  hi,

  refer below code

  for (int index = 0; index < this.Repeater1.Items.Count; index++)
  			{
  				CheckBox cbx = (this.Repeater1.Items[index].FindControl("animation1").FindControl("CheckBoxid") as CheckBox);
  				Label label = (this.Repeater1.Items[index].FindControl("animation1").FindControl("Labelid") as Label);
  			}

  Hi,

  Suppose you have the checkbox inside the repeater then you need to do somthing like:
  
                    <ItemTemplate>            
                                  <tr style="background:#faf7f7;">  
                                      <td ><input type="checkbox" runat="server" id="chkId" /></td>       
                                     <td>               
                                            <uc1:animation ID="animation1" runat="server" />     
                                     </td>            
                                </tr>    
                 </ItemTemplate>
  

  
          protected void bntDelete_Command(object sender, CommandEventArgs e)
          {
              if (e.CommandName.Equals("Delete"))
              {
                   int Id=0;
                  foreach (RepeaterItem ri in rptOrders.Items)
                  {
                      HtmlInputCheckBox chkId = (HtmlInputCheckBox)ri.FindControl("chkId");
                      Literal litID = (Literal)ri.FindControl("litID");
                      if (chkId != null)
                      {
                          if (chkId.Checked)
                          {
                             Id = Convert.ToInt32(litrID.Text);
                              ///Do your stuff here
                          }
                      }
                  }
              }
          }
  
  your button code somthing look like :
  <asp:Button ID="btnDelete" runat="server" Text="Delete Item" OnCommand="bntDelete_Command" CommandName="Delete"/>
  

  Thanks

  You can loop through the Repeater items, extract the UserControl from there  using FindControl method for you to get reference to the controls within the usercontrols.. I haven't tested on this since I'm not in my development environment but I think you can do something like below at Button Click event:

  foreach (RepeaterItem item in Repeater1.Items){
         if (item.ItemType == ListItemType.AlternatingItem || item.ItemType == ListItemType.Item){
            UserControl uc = (UserControl)item.FindControl("animation1");
            if (uc != null){
               //Access the checkbox that resides within the UserControl
               CheckBox cb = (CheckBox) uc.FindControl("CheckBox1");
               if(cb.Checked){
                  //Do something
               }
            }
         }
  }
