my page load checks if it's not postback it calls the gridview load which does what i've posted and i have seperate event handler.
|
|
|
|
|
I had the same issue. I had to literally re-bind the entire datagrid for it to work. It worked for me, and was working under time cruch, I stuck with it.
|
|
|
|
|
what do u mean by rebind, rewrite the code?

Hi ,
Your Page_Load checks if it is not a postback right ?
This means your code sets the DataSource property of your grid ONLY once and that is when the page loads for the first time.
Please write the code "grid.DataSource = dataTable;" just before the code "grid.DataBind()" and let me know if it works.
Always make it a habit to set the DataSource of a grid just before calling the DataBind() method on the grid.
E.g. I would always code method like "BindPersonsData()" in my application which would be like -
private void BindPersonsData()
{
grdPersons.DataSource = GetPersons();
grdPersons.DataBind();
}
private DataTable GetPersons()
{
DataTable dt = new DataTable();
//logic to get data
return dt;
}

Hi,
how I can get the birthday from column in database ( as datetime type ) and display it in a separate dropdownlist one for day and other for month and textbox for year .
I want get the information to update on it .
thanks .

Is it stored in the database as a DateTime? If so then you get the same way you would get any other column. Once you have the DateTime object you use the properties the structure, Day, Month, Year to get the constituent parts.
In these situations I usually rely on a little trick I like to refer to as Reading the Documentation, or as some abbreviate it, RTFM

Why you aren't using Calendar1 control?
If you have to split birthday value in controls then use Year,Month,Day SQL Functions.
e.g
select year(birthday) from mytable
select month(birthday) from mytable
select day(birthday) from mytable

no I don't need to use the calender but I need only return birthdate from database into variable as DateTime and then spilt it into day to put it in the dropdownlist , month into another dropdownlist , year into textbox to update information about user .
|
|
|
|
|
So, you can bind dropdowlists and textbox with query which I wrote you in previous post.

So you want to use three query, with all the overhead, to return one value, DateTime, which already has the properties for Day, Month, Year. Even if you combined into one query it is still unnecessary to separate the values in the SQL statement.

That was only example about Year,Month,Day SQL functions.

I want get the information to update on it .
for that task
first you have to create two dropdownlist for day and month and fill them.
then try this code
void BIndBirthDay()
{
DateTime _bdate = DateTime.Now; -- get this date from database field
int day = _bdate.Day; -- return int value(find day of datetime field like that)
drp_day.SelectedIndex = -1;
drp_day.Items.FindByValue(Convert.ToString(day)).Selected = true; -- bind that perticulare day to dropdownlist by that
}
hope this helps and also same down for month (_bdate.Day) and year (_bdate.Year)

Is this your final project? If so then the entire point is for you to make use of what you have learned and do it yourself.
If this is not a final project, then, still make use of what you have learned so far and at least try something before asking for help.

My Vote of 1 too to this poor guy. You are right, but he may also not be wrong, seeing professors in Indian Engineering Colleges.
they will teach you basics of C Programming and one day will tell you go and make a Chat application. That's very common.

It does not work like this here. This is your college project/assignment, you should put some effort.
We expect you to put some time in trying the issue that you are facing and then some time in formulating the question while posting here. Try it and tell if you face issues. Members will be more than happy to help like this.
To start with: There are lots of chat application articles here on CodeProject itself. Have a look at them (but don't copy!).
