Hi,
I current have a from with 12 textboxes, and want to index all of them,
i keep getting this error..

'System.Windows.Forms.Control.ControlCollection' does not contain a
definition for 'IndexOfKey'

I figure its because the the function IndexOfKey is not defined.. here
is the code..

for (i = 0; i < 12; i++)
{
int controlLocation = this.Controls.IndexOfKey("textBox" +
i.ToString());

//Now we access that control through the form.control
//array and set arr = the texbox.text
arr = Convert.ToInt32(this.Controls[controlLocation].Text);
}

My question is what would the definition of IndexOfKey look like, and
where would it go??

Thanks,
Jimmie

Hi Jimmie,

I can understand your confusion. I believe it arises from using a property
of the System.Windows.Forms.Control.ControlCollection class in the .Net 2.0
Framework, with a class written for the .Net 1.1 Framework. The 2.0
System.Windows.Forms.Control.ControlCollection class *does* have an
IndexOfKey method, but the 1.1
System.Windows.Forms.Control.ControlCollection does not.

Hi Jimmie,

I explained your problem but forgot to add a solution!

I would implement my own IndexOfKey method, to which you would pass an
instance of System.Windows.Forms.Control.ControlCollection, and a string
(the name of the Control you are looking for). It would loop through the
Collection, check the Name property of each Control, compare it to the name
passed, and stop when it found a match, returning the index at which it
stopped.
