I don't think even you assign Null to a DateTime variable since it will elicit a compile time error. Thatz why perhaps, we have a DateTime.MinValue in existence.

Hai

if user is not insert any
value that is myquestion

U can't insert NULL For Datetime datatype.
Check out if Date is "01-01-1900" then display "" Instead of "01-01-1900"

NULL is not an allowed value for DateTime. Your best bet is the predefined constant DateTime.MinValue.

Hai,
Just my small suggestion..This is a regular problem when using the SQl query in this way and is considered a bad programming practice.. You can make it better and free from error by doing it like below.
SqlConenction con = new SqlConnection("database=anand;server=sdiserver;uid=sa;pwd=sa");
con.Open();
SqlCommand cmd = new SqlCommand("insert into jai(name,age,genter,country) values(@name,@age,@genter,@country)",con);
cmd.Parameters.Add("@name",SqlDbType.Char).Value = Txtname.Text;
cmd.Parameters.Add("@age",SqlDbType.Int).Value = int.Parse(Txtage.Text);
cmd.Parameters.Add("@genter",SqlDbType.Char).Value = txtgender.Text
cmd.Parameters.Add("@country",SqlDbType.Char).Value = coun;
cmd.ExecuteNonQuery();
This will help you a lot when doing queries with large number of parameters.
Hope this helps

If this example is only for some demonstration purpose, then this is ok. You can accept the suggestion given by first poster. But if you are using this in a online server, It looks like you are very closer to SQL Injection Attacks. You should never write queries like this, use parameterized queries or stored procedures. To know regarding the attacks check this[^] excellent article.

Amongst all syntax and semantic errors that I would like to guide you in this query, the first and foremost to suggest you is that you should take remedial steps to solve the aggressive SQLInjection vulnerability that is blatantly visible in this code snippet.

I have a serious problem with updatepanel and checkedchanged event. When the checkbox is in the updatepanel the checkedchanged event never fires when i step through my code, even though auto postback is enabled.
Is there a little trick to this that I'm missing?
|
|
|
|
|
try adding the checkedbox to the trigger collection of the UpdatePanel
|
|
|
|
|
Above step + Make the UpddateMode to Conditional.
|
|
|
|
|
Thanks alot, that worked fine... Its odd I forgot completely that i had set it to conditional about two weeks ago, and that was causing the problem.
|
|
|
|
|
In my app there are a lot of CheckBoxes in UpdatePanels all fireing the CheckedChanged event.
Could you please post a bit of your aspx definition, otherwise it is impossible to help.
btw: I do not use the trigger collection on the UpdatePanel, UpdatePanels are all set to Conditional as UpdateMode.

hi,
in my application i have a checkbox, when user checks it n goes to another aspx page and returns to the previous page, the checkbox gets unselected...it must maintain the value.
How to do this...can anyone help?
im new to asp.net...can anyone tell me is it using sessions then how to use it..or viewstate...
|
|
|
|
|
by default asp.net handles viewstate, ,if not u can put this in the checkbox code in
EnableViewState=true

Which database?
Which language?
Use an OleDbConnection and a command object to perform a sql query and then as you loop through your results populate the list. You can find documentation on this in the MSDN.
