Class-Level Variables in Web Form

[Landley]

Hi All,

I have declared some class-level variables in a web user control. When a
button is clicked, one of these variables is set to a specific value. The
page then does a postback and the value that I previously stored in the
variable has gone.

Is there a way to keep hold of the values of these variables without using
Session variables?

If you need to maintain a value for 1 page, ViewState can help.

add variable to viewstate ViewState.Add("myvariable",myvalue)

To access the value back during postback ViewState("myvariable")

View state stores and returns object. it will need to be casted like
below before using.

int i = (int) ViewState("myvariable");
