Avoid having to use find control every time

[jgd1234567]

Hi i have a nested control i need to call in about 6 different methods. Therefore at the top of every method i have:

ListBox lbxLeftColumnAdverts = (ListBox)fvwDocument.FindControl("lbxLeftColumnAdverts");

Is it not possible to add a private variable to access this control. I tried placing the following at the top of my class:

private ListBox lbxLeftColumnAdverts = (ListBox)fvwDocument.FindControl("lbxLeftColumnAdverts");

I also tried setting it in the Page_Init method but had no joy. I'm sure this is quite a common problem but i seem to be missing something. Appreciate the help.

Thanks

Hi fvwDocument is a FormView control. I have a series of ListBox controls within the formview with buttons to re arrange items in the boxes and pass items between the various boxes.

You don't have to assign it to a variable. You could just access it directly with the FindControl method.

you can't do this directly FormView.FindControl("...") if your not looking for a container. (at least i don't think you can.)

instead you need to access the FormView's container and then call FindControl();

FormView.ItemTemplate.FindControl("...");

Hi, sorry i think you might be mis-undertood me. I simply wanted a way of not having to declare:

ListBox lbxLeftColumnAdverts = (ListBox)fvwDocument.FindControl("lbxLeftColumnAdverts");

at the top of every method which uses the lbxLeftColumnAdverts control (which is within the formview control) as i feel it's abit long winded. I hoped i could just set a class level variable instead. If there's no solution then i guess i'll have to put up with it.
