Disable input editing

• Sometimes we need disable input for editing, but property readonly disallow send data from server (for example, when we use calendar extender).
• Example shows how we can disallow editing via javascript.

<asp:TextBox ID="txb_Date" runat="server" onKeyPress="javascript: return false;" onPaste="javascript: return false;" />
<ajaxToolkit:CalendarExtender ID="txb_Date_CalendarExtender" runat="server" PopupButtonID="txb_dateFrom" TargetControlID="txb_Date">
</ajaxToolkit:CalendarExtender>

• Access date from calendarextender when readonly property is set.

txb_Date.Text = Request[txb_Date.UniqueID];
