Hi,
I have the following code in my asp page. I would like to click on Select button and get the logoid which is in a hidden field. but it won't work when i click on the button.
             <telerik:RadListView ID="dvlogo1" runat="server" DataSourceID="dslogo"
            ItemPlaceholderID="PlaceHolder1" AllowPaging="true" OnItemCommand="dvlogo1_ItemCommand" >
            <LayoutTemplate>
                <div class="sushibar">
                    <asp:Panel ID="SushiPanel" runat="server">
                        <div class="sushi">
                            <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
                        </div>
                        <telerik:RadDataPager ID="RadDataPager1" runat="server" PageSize="10" Skin="Black">
                            <Fields>
                                <telerik:RadDataPagerButtonField FieldType="Numeric" />
                            </Fields>
                        </telerik:RadDataPager>
                    </asp:Panel>
                </div>
            </LayoutTemplate>

                     </p>

                </div>
            </ItemTemplate>

                     </p>
                </div>
            </SelectedItemTemplate>
        </telerik:RadListView>

C# Code
         protected void dvlogo1_ItemCommand(object source, RadListViewCommandEventArgs e)
        {
            if (e.CommandName == RadListView.SelectCommandName)
            {
                RadListViewDataItem item = e.ListViewItem as RadListViewDataItem;
                string myValue = item.GetDataKeyValue("logoid").ToString();
            }
            //switch (e.CommandName)
            //{
            //    case "selectlogo":
            //        Session["logo"] = e.CommandArgument;
            //       // hid = (this.dvlogo1.FindControl("hidlogoid") as HiddenField).Value;
            //        Session["logoid"] = (this.dvlogo1.FindControl("hidlogoid") as HiddenField).Value;

            //        break;
            //}
        }

I appreciate your help very much.

Hello Kamal,

You should use the current item as a search container instead the entire RadListView instance.

if (e.CommandName == RadListView.SelectCommandName)
{            
    Session["logoid"] = (e.ListViewItem.FindControl("hidlogoid") as HiddenField).Value;
}

Best wishes,
