Pass control as ref?

[crazyboybert]

Hi all

Is it possible to pass a control as a ref to a method of another class? For example..

public void fillList(ref System.Web.UI.WebControls.DropDownList myList){
  //open a database connection and command object
  myList.DataSource = myCommand.ExecuteReader();
  myList.DataBind();
  //close connection
}

then calling method above from webform

System.Web.UI.WebControls.DropDownList myList = new System.Web.UI.WebControls.DropDownList();
namespace.classname.fillList(myList);

I have tried the above but don't seem tobe able to pass a control. I guess you are only allowed to pass variables? Would make sense...Is there anyway other way to databind to a control on a webform from a method in a different class?

Cheers

Passing a control by reference should work fine. What error are you getting? Or maybe there is something wrong with the database command?

Sorry for no reply - been having trouble getting into the forum?

Error is something like...

"Cannot convert System.Web.UI.WebControls.TextBox to type ref System.Web.UI.WebControls.TextBox"

Database command is ok as returns datareader to webform fine but wont accept control as ref to be updated form reader by class...

Any ideas?

Thanks
