help me prove my reference book is incorrect

they might not have option strict on

[mattglet]

in my asp.net reference book that i'm using to learn this language (i'm not going to list the actual title... not sure if it's against TOS), they show this example:

dim EditText as Textbox
EditText = E.Item.FindControl("txtBlah")

when i enter that into my code (of which i have Option Strict turned on), i get this error:
"Option Strict On disallows implicit conversions from 'System.Web.UI.Control' to 'System.Web.UI.WebControls.Textbox'."

i am referencing values from a datagrid, and using FindControl to pull the values to then add to my datatable. do the writers of my book not use Option Strict in this example, or am i doing something wrong?

Not sure in VB.NET but in C# that code shouldnt compile since you cant implicity cast a Control to a TextBox.. for that code to compile you would have to do this:

TextBox editBox;
editBox = (TextBox)e.Item.FindControl("txtBlah");

So yeah, I would imagine that you are correct.

That's right. The authors have Option Strict off. With Option Strict on, you have to do:

Dim EditText as Textbox  
EditText = CType(E.Item.FindControl("txtBlah"), Textbox) 

or slightly more efficient:

Dim EditText as Textbox  
EditText = DirectCast(E.Item.FindControl("txtBlah"), Textbox) 

BTW, no problem listing the title of the book! Just don't link to Barnes and Noble or Amazon with your affliate code.

xoc-

worked as you described, thank you.

now i have a new problem... when i use FindControl, it pulls the original value of the textbox, and saves THAT (as opposed to using the updated textbox value). but if i use Request.Form.Item(3).ToString, it works perfectly. any idea why FindControl isn't working?

yes, it's totally off the wall, and should not be happening this way, i know this :)
