  How can i hide certain ListItems ?

  Apr 30, 2012 12:20 AM|LINK

  Hi ,

  currently i dynamically assign list items and the type is a "checkcolumn". Now each item has a checkbox and value text .

  If the value text selected is "ALL" i would like to make the others non selectable or disabled ..

  how can i do this if the listitems doesnt have an "enabled" property.

   

  cheers

  Hi sorry for that .. here is what id do

   <dx:ASPxListBox ID="lbxSunCo" runat="server" OnDataBinding="lbxSunCo_DataBinding"                                 SelectionMode="CheckColumn" TextField="Name" ValueField="Code"   ClientInstanceName="checklistBox"                                 Width="100%" Height="140px">                                 <ItemStyle BackColor="White" ForeColor="Black"></ItemStyle>                                                                                                   <ClientSideEvents SelectedIndexChanged="function(s, e) {                                                                                var item = checklistBox.GetSelectedItem();CallbackPanel.PerformCallback('1');}" />                                                           </dx:ASPxListBox>

   

  and on the code behind id do the following

  
  protected void ASPxCallbackPanel1_Callback(object source,DevExpress.Web.ASPxClasses.CallbackEventArgsBase e)

          {

  for (int i = 0; i < lbxSunCo.Items.Count; i++)

              {

                 if (lbxSunCo.SelectedValues.Contains("All"))

                  {

                      RemoveAllItems();

                      RebindLbxSunCo();

             break;

                  }               

              }          

          }

  
  

  protected void RebindLbxSunCo()

          {

  for (int i = 0; i < lbxSunCo.Items.Count; i++)

              {

                  lbxSunCo.Items.RemoveAt(i);

              }

        IList<IFwDatabase> sortedList = new List<IFwDatabase>();

        IFwDatabase database = new FwDatabase("All", "All");

              sortedList.Insert(0, database);

              lbxSunCo.DataSource = sortedList;       

          }

  protected void RemoveAllItems()

          {                    
  for (int i = 0; i < lbxSunCo.Items.Count; i++)

              {             

               lbxSunCo.Items.RemoveAt(i);

              }       

  }

   

  cheers
