<mm:mmTextBox ID="txtClientNumber" runat="server" BindingSource="Client" BindingSourceMember="ClientNumber" OnTextChanged="txtClientNumber_TextChanged" AutoPostBack="True" Width="92px"></mm:mmTextBox>I want that the txtClientNumber_TextChanged fires whenever the text changes in this textbox. However, the code fires only the first time the text changes, but I want it to fire every time.
