RadSearchBox searchText length on DataSourceSelect is not correct

[Iago]

Hello,

I am using a RadSearchBox with   MinFilterLength="3". I am interested in filtering my search in OnDataSourceSelect, but even when I type 4 characters, this method: 
   protected void RadSearchBox1_DataSourceSelect(object sender, Telerik.Web.UI.SearchBoxDataSourceSelectEventArgs e)
        {
            string searchText = e.FilterString;
           
        }
e.FilterString.Length returns 3 and RadSearchBox1.Text.Length is also 3 inside the method RadSearchBox1_DataSourceSelect

This is not narrowing enough my result set and I do not want to set MinFilterLength="4" because I have to allow also searchs by 3 characters.
Any suggestion will be welcome. Thanks in advance.

Hello Iago,

Please find attached a sample project implementing the approach from the OnDataSourceSelect event article, which shows the correct filter string as demonstrated in this screencast.

If that does not help to resolve the issue, please modify the attached project so that it replicates it and send it back to us in an official support ticket. This would allow us to investigate locally and help you more efficiently.
