  I have a RadListView and within the listview I have an asp.net linkbutton. I want to dynamically set the linkbutton's PostBackUrl. I can achieve this if I find the linkbutton control in the listview's ItemDataBound event. But by doing this when I end up clicking on the linkbutton the listview ItemCommand event is not being fired. I need the itemCommand even to be fired so I can take the datakeyvalue of the item clicked and set it into a session variable to pass to teh postbackurl page of the link button.
  
  

  <telerik:RadListView ID="lstVwWebpageList" runat="server" EnableViewState="true" ItemPlaceholderID="webpageContainer" AllowPaging="true" DataKeyNames="id" Skin="WebBlue" OnItemDataBound="lstVwWebpageList_ItemDataBound" OnPageIndexChanged="lstVwWebpageList_PageChange" Width="607px" OnItemCommand="lstVwWebpageList_ItemCommand">

      <LayoutTemplate>

          <table cellpadding="0" cellspacing="0">

              <tr>

              <td>

                  <asp:PlaceHolder ID="webpageContainer" runat="server" />

              </td>

              </tr>

              <tr>

              <td>

              <telerik:RadDataPager ID="Pager" runat="server" PagedControlID="lstVwWebpageList" PageSize="50" Skin="WebBlue">

                  <Fields>

                      <telerik:RadDataPagerButtonField FieldType="FirstPrev" />

                      <telerik:RadDataPagerButtonField FieldType="Numeric" />

                      <telerik:RadDataPagerButtonField FieldType="NextLast" />

                  </Fields>

              </telerik:RadDataPager>

              </td>

              </tr>

          </table>

      </LayoutTemplate>

       

      <ItemTemplate>

          <fieldset style="float: left; width: 300px;">

              <table cellpadding="0" cellspacing="0">

                  <tr>

                      <td>

                          <table cellpadding="0" cellspacing="0">

                              <tr>

                                  <td style="width: 25%;">

                                      <b>Name:</b>

                                  </td>

                                  <td style="width: 75%;">

                                      <asp:Label ID="lblName" runat="server" Text='<%# Eval("name") %>'></asp:Label>

                                  </td>

                              </tr>

                              <tr>

                                  <td style="width: 25%;">

                                      <b>Page:</b>

                                  </td>

                                  <td style="width: 75%;">

                                      <asp:LinkButton ID="pagenameLink" runat="server" CommandName="LinkClicked" Text='<%# Eval("pagename") %>'></asp:LinkButton>                                   

                                  </td>

                              </tr>

                          </table>

                      </td>

                  </tr>

              </table>

          </fieldset>

      </ItemTemplate>

  </telerik:RadListView>

  
  
  

  protected void lstVwWebpageList_ItemDataBound(object sender, RadListViewItemEventArgs e)

     {

         LinkButton link = (LinkButton)e.Item.FindControl("pagenameLink");

         Label lblname = (Label)e.Item.FindControl("lblName");

   

         link.PostBackUrl = "EditWebpage.aspx?name=" + lblname.Text + "&page=" + link.Text;

   

         //RadListViewDataItem item = (RadListViewDataItem)e.Item;

         //Session["linkID"] = item.DataItem;// Convert.ToInt32(item.OwnerListView.DataKeyValues[item.DisplayIndex]["id"]);

     }

   

     protected void lstVwWebpageList_ItemCommand(object sender, RadListViewCommandEventArgs e)

     {

         if (e.CommandName == "LinkClicked")

         {

             RadListViewDataItem item = (RadListViewDataItem)e.ListViewItem;

             Session["linkID"] = item.DataItem;// Convert.ToInt32(item.OwnerListView.DataKeyValues[item.DisplayIndex]["id"]);

         }

     }

  Hi Adam,
  
  The Item command event is not fired because you are making a redirect to a different page. Just get the data key value in the ItemDataBound event and set it as a query string parameter in the url of the page which the list view is redirecting to.
  
  Hope it helps.
  
  All the best, Tsvetoslav
