WebCombo callback functionality

 Hi there

Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";}

Somebody can help me with the load-on-demand feature at run time in v8.2 of WebCombo. I’m following the help guidelines but something might be wrong, the Combo doesn’t load on demand, only the first required rows, in this case 10, when you scroll down dosn't load the other records. Here you can see the code:

 

        protected void Page_Load(object sender, EventArgs e)
        {
            this.WebCombo1.EnableXmlHTTP = true;
            this.WebCombo1.DisplayValue = "ShortName";
            this.WebCombo1.DataTextField = "ShortName";
            this.WebCombo1.DataValueField = "CCode";

            this.WebCombo1.DropDownLayout.RowsRange = 10;

            this.WebCombo1.InitializeDataSource += new InitializeDataSourceEventHandler(WebCombo1_InitializeDataSource);
        }
 

 

       void WebCombo1_InitializeDataSource(object sender, WebComboEventArgs e)
        {

            //Here I load a dataset with the table Countries


             this.WebCombo1.DataSource = _datasetmain.Tables["LUP_Countries"].DefaultView;
            this.WebCombo1.DataBind();

        }

 

I'll appreciate any help.

regards
