insert into table (dob) values ('" + datetime.parse(txtdob.text).TosSring("yyyy-MM-dd") + "')

What is "TosSring"? That should be a red flag right there.

use this

IFormatProvider Provider = new System.Globalization.CultureInfo("en-US", true);
convert.toDateTime(txtdate.text,provider)

Try this:

DateTime doj = new DateTime(); 
System.Globalization.CultureInfo c1 = new System.Globalization.CultureInfo("en-GB", true);
            doj = DateTime.Parse(txtdob.Text.Trim(), c2, System.Globalization.DateTimeStyles.NoCurrentDateDefault);

and insert like this

C#

insert into table (dob) values ('" + doj.ToShortDateString()+ "')

I would suggest to use

XML

<asp:TextBox ID="txtStartDate" runat="server" Width="31%"></asp:TextBox>
                 <Ajax:calendarextender id="CalStartDate" runat="server" format="yyyy-MM-dd" targetcontrolid="txtStartDate"></Ajax:calendarextender>
                 <asp:Label ID="lbl_Validate_SD" runat="server" ForeColor="Red"></asp:Label>

Thats the reason experts always recommend to use ISO 8601 date format for server side processing. Check this

ISO_8601[^]

I would suggest to use stored procedure[^], instead the queries in code behind.
There are 2 resons:
1) possible SQL Injection[^]
2) date time format depends on localization[^] (culture).

Ad 1)
How To: Protect From SQL Injection in ASP.NET[^]
Stop SQL Injection Attacks Before They Stop You[^]
SQL Injection and how to avoid it[^]

Ad 2)
Globalizing and Localizing .NET Framework Applications[^]
How to: Set the Culture and UI Culture for ASP.NET Web Page Globalization[^]
Formatting Date and Time for a Specific Culture[^]
Formatting Numeric Data for a Specific Culture[^]

Finally, your stored procedure might looks like this:

SQL

CREATE PROCEDURE InsertMyData
    @myDate DATETIME
AS
BEGIN
    --temporary change 
    SET DATEFORMAT ymd; --or dmy or mdy
    INSERT INTO TableName (Field) VALUES(@myDate)

END
