ItemsRequested not work correctly

[Camila Foltran]

I am using server side code to populate the combobox. and enabled "EnableLoadOnDemand"
The combobox doesnt seem working correctly. When the page first opens, click into the combobox nothing hapens and it is not populated. When I type in something or delete what i typed in then it populates. I tried to change the code to as simple as assigning a datatable to the combobox datasource still no luck..
why? what I do?

Camila:

Can you tell us what browser you are using to test this? There does appear to be some open issues related to Internet Explorer 9 (see here).

Would it be possible for you to post your form definition and server-side code? This would help in identifying what is going wrong here.

Hello,

I have tried to reproduce the issue but no avail. Here is the code I have tried.
ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server" EnableLoadOnDemand="true" AutoPostBack="true" LoadingMessage="Loading.." MarkFirstMatch="true" AutoCompleteSeparator="," OnItemsRequested="RadComboBox_ItemsRequested">
</telerik:RadComboBox>

CS:

protected void RadComboBox_ItemsRequested(object sender, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)
    {
        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ToString());
        String s = "select FirstName,EmployeeID from Employees";
        con.Open();
        SqlDataAdapter dr = new SqlDataAdapter(s, con);
        DataTable dt = new DataTable();
        dr.Fill(dt);
        con.Close();
        RadComboBox1.DataSource = dt;
        RadComboBox1.DataTextField = "FirstName";
        RadComboBox1.DataValueField = "EmployeeID";
        RadComboBox1.DataBind();
    }

Note: Make sure that you have tried with the version which supports the latest browser.

Hope it helps.
Thanks,
Princy.
