Re: Setting a Default Value

Put this in a class somewhere.



public static string SafeSessionGet(Page pageObj, string requestKey,
string defaultValue)
{
if (pageObj.Request[requestKey] == null)
{
return defaultValue;
}
else
{
return pageObj.Request[requestKey].ToString ();
}
}




public static string SafeSessionGet(Page pageObj, string requestKey)
{
return SafeSessionGet ( pageObj , requestKey , string.Empty ) ;
}





You could write a generics version of this in 2.0 if you wanted, but that
might be overkill.


private string m_empUUID = string.Empty;

public void Page_Load(object sender, EventArgs e)
{


m_empUUID = SafeSessionGet ( Page , "empkey" ) ;
//or

m_empUUID = SafeSessionGet ( Page , "empkey" ,
"00000-00000-000000000-000000000" ) ;



}

I have an asp.net/csharp application that requires a particular variable
to
work properly. This variable is usually passed via a query string in the
URL
when the application is first run but under certain circumstances the
query
string may not contain the variable. So I need some way of establishing a
default value if one isn't set.

Is there some way I can set a query string on page_load OR is there some
way
I can use a global variable which is accessible throughout my application
instead? In pseudo code something like:

public void Page_Load(object sender, EventArgs e)
{
if (querystring == null)
{
global myvariable = "somevalue";
} else {
global myvariable = querystring;
}
}

protected void dostuff(object sender, EventArgs e)
{
if (myvariable == "foo")
{
// do stuff
}
}

Hopefully this makes sense - for clarity sake I have tried to simplify my
situation as much as possible.

Thanks
Brad
