MyClass.prop1 = doingsomething("test1");
MyClass.prop2 = doingsomething("test55");

I want to do something like this:
foreach(ClassInfo)

On my form I refresh a dataset in the Page_Load() event. But I also have a filter button which changes the dataset and reloads it. When the user clicks a button, the dataset gets refreshed twice. I would like to modify the Page_Load() event so that if the page is being reloaded because of a button click event, then I will skip refreshing the dataset in the Page_Load() event. Is it is possible to determine that the page is reloading due to a button click event?

I have a public property defined in code behind of a user control. I want to toggle visibility of controls in the markup based on the property's value.
However, using the following syntax:
<td style="display:<%#(Container.PageControlMode == PageControlMode. PageMode.Wizard) ? "none" : "inline" %;">
I have the following property in my code behind:
public PageMode PageControlMode { get; set; }
Does not work and generate errors.
suppose i've created my own user control, and it has a textbox and a property for the textbox so that if i use the user control from within the aspx file, i can give the property a value. for example:
[Code]....
is it possible to also set the property to be seen via the desing mode , just as it works for other (built in) controls? maybe a different method to implement the same scenario?
if you still didn't understand what i mean : after setting the value of DefaultNum1 via the code i've written here, i expect the textbox associated with this property to be updated as well to '1' via the design mode (and split mode). of course it won't work using the current method, since VS cannot guess what is going on with the property and understand that all of its purpose is to assign an initialization value for the textbox.

I work with dynamic webuser controls. Depending on a choice in a dropdownlist, I load the webuser controls from my database. In the Page_Load event, I load the controls. When the controls are loaded and a button is pressed, the values that are filled in,in the webuser controls' textboxes, must be saved in the database. when I click the button, the values of the textboxes are empty again. Here's my code:
