Answer 1

You should not set the property ReadOnly="true" on your TextBox.

If TextBox's ReadOnly property is "true", postback data won't be loaded eg it essentially means TextBox being readonly from server-side standpoint (client-side changes will be ignored). If you want TB to be readonly in the "old manner" use

TextBox1.Attributes.Add("readonly","readonly") 

as that won't affect server-side functionality.

For more information follow StackoverflowAnswer or TextBox Readonly problem.

Why don't you set the date time format in .cs file itself. Look here http://msdn.microsoft.com/en-us/library/system.windows.forms.datetimepicker.customformat%28v=vs.110%29.aspx

Answer 3

before <asp:Content> add this line

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

After <asp:Content > add

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
    </asp:ToolkitScriptManager>

To solve this set the CalendarExtender's SelectedDate in the textbox.Text data = change to whatever it is in the textbox and it will stick. Setting SelectedDate sets the textbox field at the same time.

Easy fix example

'protected void txDate_TextChanged(object sender, EventArgs e)
{ 
        txDate_CalendarExtender.SelectedDate = Convert.ToDateTime(txDate.Text);
}'
