Adding a new combobox after selecting an item

[TANSERI]

Hi,

I have created a combobox load on demand and I want to add an another combox box when I select an item of the first combo box. The second combo box must use the selected value of the first combo box to execute an SQL query and to retrieve items.


When I select an item of the first combo box, the second combobox is added, but when I open it, a popup is displayed.

Here is the code of my issue.

Thanks a lot.

protected void Page_Load(object sender, EventArgs e)
   {
       ComboBoxLoadOnDemand cbx = new ComboBoxLoadOnDemand();
       cbx.TableName = "ddl_report_collaborator";
       cbx.DataTextField = "text_ddl";
       cbx.DataValueField = "value_ddl";
       cbx.Height = Unit.Pixel(250);
       cbx.Width = Unit.Pixel(200);
       cbx.NbItemsRequested = 50;
       cbx.AutoPostBack = true;
       cbx.ShowMoreResultsBox = true;
       this.form1.Controls.Add(cbx);
       cbx.SelectedIndexChanged += new Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventHandler(cbx_SelectedIndexChanged);


   }
   void cbx_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
   {
       ComboBoxLoadOnDemand cbx2 = new ComboBoxLoadOnDemand();
       cbx2.TableName = "ddl_report_collaborator";
       cbx2.DataTextField = "text_ddl";
       cbx2.DataValueField = "value_ddl";
       cbx2.Height = Unit.Pixel(250);
       cbx2.Width = Unit.Pixel(200);
       cbx2.NbItemsRequested = 50;
       cbx2.ShowMoreResultsBox = true;
       this.form1.Controls.Add(cbx2);
   }

Hello TANSERI,

I've tried to reproduce this issue but to no avail. Could you please open a support ticket and attach a simple page demonstrating the issue there? Thanks
