"Setting the focus to the end side of TextBox" is the exactly same thing as "setting the focus in any other place of TextBox". The notion of focus means keyboard focus and is related only to the control. Don't mix up focus and selection.

While you can use the method System.Web.UI.WebControls.TextBox.Focus, you cannot control text selection using this control. This is possible in WPF and System.Windows.Forms, not in APS.NET.

See http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.textbox.aspx[^].

Solution 3

instead of TextBox you can use Textarea and can achieve this functionality using javascrip

Have a look on that javascript getting and setting caret position in textarea/[^]
