Compact Framework 3.5 referencing user control error

Question

I have a compact framework application [vb.cf] running on windows CE platform. I have a user control that I add multiple times to my to my form , to form a grid, in run-time.

I am now trying to access and set the properties on my user controls and using the ;

Dim mod_prop As ctl_mod_table = CType(Me.pnl_table.Controls("ctr_" & icount), ctl_mod_table)

This produces the following error :

Conversion from string "ctr_1" to type integer is not valid???

Any reason why I get this?

I DO NOT WANT TO USE A LOOP ALL CONTROLS procedure as this is slow.

Why not just keep your controls in a list so you don't have to find it later? — Alan, Aug 29 '14 at 14:10

In the Compact Framework you must search the controls by name manually. This SO question has a CF-specific answer.

this.Controls.Find is not support by cf.net [compact framework]. this is my underlying problem. :( – MackieRSA Aug 28 '14 at 14:09
As Chris said, look at the specific answer talking about Compact Framework! – Nicolas R Aug 28 '14 at 15:49

your Controls(...) is using an index value, so an integer. Here you are trying to pass a string variable, ctr_1, which is obviously... not an integer.

You need to access your control by its name, try simply to call Me.Controls("ctr_" & icount) instead of Me.pnl_table.Controls("ctr_" & icount): you will look at the controls of the form.

Thanks for this. The reason I use me.pnl_table.controls is because my user controls are inside a panel called pnl_table. Does this makes a difference? – MackieRSA Aug 28 '14 at 11:19
