List<> Shows Different Values entered in the textbox [Resolved]

Good Day All

i have 20 Textboxes i am not sure what did i touch by i normally dont play with VS Settings i dont understand. So those textbox are normally defined like this

<asp:TextBox ID="txtUnitLen20" onKeyUp="Jump()"   runat="server" 
                    TabIndex="19" AutoPostBack="True"></asp:TextBox>

and i am adding the value of a Textbox to a List<string>

SerialsText.Add(txtUnitLen1.Text);

but if the value that is entered is "1" , there i will get this as a Value hex like this

[0x00000001] = "1"

Please note that the Textbox gives me "1" but the List gives me those Numbers


Thanks
