hi,
I mean to say that suppose user add a item whose product_id is "CB920". Now user again enters the same item then only the quantity should be updated. This code will only work if there will be atleast one row already in the cart.Then when the next item will come this function will check the datatable for the particular row. If found then it will update the quantity otherwise it will add a new row.
This I want to do.
cheers,

hi,
Actually what is your task,
DataRow myrow = dt.NewRow();
myrow["REF"] = id;
myrow["Description"] = desc;
myrow["QTY"] = quanti;
myrow["Price"] = unitprice;
myrow["Cost"] = cost;
int dtcount = dt.Rows.Count;
if (dtcount > 0)
{
DataRow[] arrMatchingValues = dt.Select("REF=" + id);
in this code your searching for the id which is added to same datatable previously...
|
|
|
|
|
if your getting any error after debug plz.. write that error..
in this you will get only one row ......
|
|
|
|
|
hi,
Thanks for your response.
Actually it is giving the error in the filter expression term. The error is
"There is no column named [CB920]"
This is id of the product which user is selecting.
cheers,

in this first you have to create column for dt.
ex:dt.column.add[...];
after that write this code.
DataRow myrow = dt.NewRow();
myrow["REF"] = id;
myrow["Description"] = desc;
myrow["QTY"] = quanti;
myrow["Price"] = unitprice;
myrow["Cost"] = cost;

Hi,
But I have five fixed columns(REF,Description,QTY,Price,Cost).And row matching is done as per "REF" column which is already there.
And at the 0th position of the datatable the column name is "REF"
Please tell me which you are talking about.
cheers,

Hi Sneha,
Any way you are binding to the data to Gridview. so, you can do updating the data in gridview. then it will works fine.
Actually, for data table you can't set datakeys value as we can do for gridview. cehck it out.

You are an absolutely ignorant moron. Contact your client or your boss, tell them you are a liar and a thief for claiming to know how to program, then find a new job.
I told you the answer to this days ago. It appears you were incapable of googling my answer, or replying to ask me for more help. What's the point in asking again if you're too dumb to understand the answer ?

in my website i have to folders. in that two folders i put two web.config files for each one.
And in root folder i put another web.config file in that i write below code
<forms name="auth" loginurl="./pages/Userlogin.aspx" defaulturl="./pages/UserVotings.aspx">
Now i want to user this authentcation in above two folder but. here.
for folder1 i have different login url and defaulturl.
and for folder2 i have different login url and default url.
how to apply root web.config to those to folders web.config
|

You mean you have 2 web config to two subfolders of your virtual directory, and you want to remove them and want to use a single web.config to handle both of them from root.
I think you can have 2 different appsettings key to handle this, so that if the url contains the foldername apply one otherwise some other...
You need to do the checking programatically.

Buy an ASP.NET book and read it. Make sure you read the chapter on the session object.

Hi,
Inorder to display the login name of the user:
1.First, add a master page and include all the child pages for it.
2.Put the control u wish to display in every page outside content page(if u put the control in it, u cud c tat only in the master page)
3. Aftr a user logs in , the username shud b got into a Session variable (eg: Session["uname"]= username ) and this session var.'s value is assigned to the control(eg:label)
Bingo ! there goes the question.
Good Luck!!

to display user name in master page. just put one lable in master page and in master page Page_load event.
just assign the session to lable
ex: lblusername.text=Session["username"];
|
|
|
|
|
I did it as u told Like user.text = Session["pho"].ToString();
But during runtime it assign the master page variable first and give a error called
Use the new keyword to create an object instance. can u correct it?
|
|
|
|
|
Actually in Vb.net this is the solution for that, but i don't know in c# .net
If Not Page.IsPostBack Then
If Not Session("username") Is Nothing Then
lituser.Text = Session("username")
End if
End if
|
|
|
|
|
I am again suggesting you please buy a Basic ASP.Net Book Or Please read some Article on Session.
