Sharing Data Between Forms

[kcowley]

I have two forms, the first has a textbox with customer name (read only) and a button to load the second form which has some textboxes for enter customer name, etc. When I populate these textboxes from SQL and click ok to close the second form I want the customer name from a textbox to return to the first form.

How do I do this? Return values? Global variables? Any help would be greatly appreciated!

try using the hidden control, declare a html contol of type hidden, then set its value on the Form2 , when you reopen the form 1 you can get the value using Requets("hdnControlName");

Or set a session variable... or cookie, though I would suggest session variables just because I am partial to them.


Session["FirstName"] = "HisName";
...
string FirstName = (string)Session["FirstName"];

Is this a web application or a windows application?

There is a sticky at the top of the forum the begs people to post correctly. Please read it as it sets a format for discussion titles.

The suggestion is good, however please note creating a session or cookie require utilization of resource at client end, beside this making severe use of session variable is not a good practice.
In case if user wishes to create a session/cookie then please do abandon the session/delete the cookie once its use is over.

Please see this article on what Sessions are and how to use them

This is true, but it also takes some of the load off the server, which is why I am partial to them.

Good points though

Why don't you just create a class with friend shared variables and use them in the other form?
