dynamic control names - fill controls in loop [dynamic control names - fill controls in loop]

jogisarge — Mon, 29 Jun 2009 06:34:43 GMT

Hi,

i have a form with controls that show productinformation.
now i have 10 textboxes named tbxPrice1 -> tbxPrice10 .

in my artikecleobject exists a property list<articleprice> named articlepricelist that could have 0 till 10 elements.

now i want to fill my 10 textboxes in a loop against my articlepricelist property.

If the articlepricelist contains 3 elements, the first 3 textboxes tbxPrice1,tbxPrice2 and tbxPrice3 should be filled.
If the articlepricelist is empty, no textbox should be filled.

Has anybody an idea, how to do this ?

Hi,

i have a class "user" that implements INotifyPropertyChanged.
with databinding i bind a objekt user1 to textboxes on a winform.

If i change the properties from user1, the textboxes will be updated.

Now i have a function that returns an objekt(user).
user1 = getuser(); -> no changes in the textbox.
with debugging i see, that the setter was not called.

How can i get this done ?
i want to see the returned data in my textboxes.

bye jo

Hi,

i have an application with my own Login-System.
when a user starts the app and logs correct in,i want to store user-data in a class "Userinformation".
other information like application-rights and so on should be also stored in this class.
my application is coded in 3-tier architecture with one assembly each tier.
i have to access the Userinformation class in many other forms - also in the business tier.

How could this be done ?
I know that global Vars are not allowed in C#, but how can i get this problem done ?

i had the idea to create a dataset, that has tables for this information ?
