Hi folks,
I want my datatable to persist through diff function calls, but I can not use static datatable as it not read only. Neither I want to use session coz its an overhead.
Is there any other way to do this...
I know the forum is full of great techies, someone might be kind enough to help.

Hi joindotnet,
what do you want to achieve exactly?
You could store the datatable into a static dictionary, using guids as keys. This guid could be attached to a hidden field, that the web form always transport. I know this is how sessions work, but this is more a lightweight implementation.
<br />
static Dictionary<guid,> dictTables = new Dictionary<guid,>();<br />
<br />
public void MyFunction() {<br />
Guid oGuid = new Guid(this.MyHiddenField.Value);<br />
DataTable oCurTable = dictTables[oGuid];<br />
}<br />

Hi Sebastian,
Thanks for ur help.Could u plz tell if I implement this solution my table would not be shared and each user would have her own copy.
Can I have a more detailed description or a link where I can understand the working of dictionary.
I would be so nice of u...
Thanks again

Hi,
for a description of a dictionary have a look here http://msdn.microsoft.com/en-us/library/xfhwa508.aspx[^].
The table itself will not be shared, but the dictionary. You have to be careful by using this because you have to manage (cleanup etc.) all by yourself. Also the static dictionary will only live as long as the IIS-process is running (which will be recycled every 24 hours, am I right?). But why don't you want to use sessions? (The solution I proposed is a kind of self-implemented session).

Thanks alot for the link.I ll try this.
I am already using session for the solution but it's making my site very slow as my datatable is very large.
When a user will use it on a dial up connection it would suck him up.
Dossn't session slows the site down??
I mean I don't know I have read it at many places.

If it is to be for many users (i.e. the same), have you looked at using the .net Cache?

Using the session is the best way to create a per user object. A static variable will be the same for all users.

Hi Christian,
yep you're right, but as I understood the question he wants the datatable to be not the same for all users. Thought using a static dictionary storing the datatables would be a better way...
By the way: Don't know nothing about that the session is slowing down the site. Did you heard something like this before?
Kind regards
Sebastian

Session store data on server side, so it can causes performance overhead. But Its depends on your data size of session. You can Enable Trace of your page and Check the Session Data Object Size.
Good luck !!!

You have one more option to use some application variable and if you have to use on same page(if UI page) then you can use viewstate too.

Gridview having some values say column1 have name and column2 have empid. I need to check all this empids and
make sure that they start from 1 and are in order.
No number is missed out in middle. If missed out, then an alert should be shown that saying the order is not proper.
Any help please.....
I have the values in Dataset but, how can i show the alert in asp.net ?

For showing an alert you have only option to use Javascript alert you can register it for the alert message and for checking the proper sequence you can check it in RowDataBound event.

take a varaible in viewstate.increase it one by one and check from the actual value like
object temp = DataBinder.Eval(e.Row.DataItem, "empid");
and check it temp from the viewstate's value if flase register an javascript alert.
Cheers!!

This appears increasingly unlikely to me.
If you're telling the user that the data they entered is invalid, you can use a custom validator, or you can use an alert. If you're checking the data in the DB, you can just use a label. Is the user entering data ? If so, just reject data that doesn't follow your rules. Hell, it's fundamentally broken that you have such a rule and you don't just auto generate the ids according to the rule set.

There is two way, you can store image path on database, or can store image directly in DB.
But How ? Just Try google. You will find lots of codes

I guess it's because you can't spell that you can't use google. Try 'SQL Server store bitmap ASP.NET'
