Dynamically Loading user control

[Beegee]

Hi
Happy 2006

I want to load the user control dynamically. I want to change to different
usercontrol page to the same place holder accordingly.

If there is no way to do so anyone please suggest me how to evaluate a
string of expression.
I have used the same in VBscript and javascript.
e.g.

stringvariable1 = "TemplateTopUserControl";
stringvariable2 = "\"TemplateTop.ascx\"";

"this." + stringvariable1 + " = (" + stringvariable1 + ")this.LoadControl("
+ stringvariable2 +")"

I want this to be executed as

this.TemplateTopUserControl = (TemplateTopUserControl)
this.LoadControl("TemplateTop.ascx");

I know that we can use eval function available in javascript so I want to
know the equivalent in C#.
Thanks very much

Beegee,
..NET does not have the equivalent of an "eval" keyword as it is a compiled,
not an interpreted language / runtime.

If you want to provide something similar to scripting capabilities in your
app, you can compile your code on the fly into an in-memory assembly.

Another option would be to use either an interface, or a static Hashtable of
the keys / names of the controls to load, and have a switch or a set of if
-else statements to determine what to pass to the LoadControl method.
