Values disappearing in hidden textbox inside repeater

[Guest]

H

Im self learning asp.net, so I may be doing mistakes. But I found something that may be a "bug"...at least for me it looks as inconsistent

I explain myself. I have a repeater and inside of it I have hidden textboxes (visible="False") with values that are set during runtime (I do a loop in a datareader to set them). If I trace the code, you can see that the values are assigned to this textboxes correctly. Once I postback the form I try to get the values from the textboxes that are inside the repeater ( I do a recursive findControl on the repeater to find the control and then grab its value). Instead of getting the value I gave to the textbox during run time I get the value that I set it to during design time in the HTML view ("0")

If I set the control to "visible="true"" for testing purposes the control is read properly in runtime and it has its value is what was expected

What it really puzzles me is that outside the repeater I do the same thing with a textbox that is hidden -in the main form- and I can get the correct value of it, even if the visible value is set to false

Isn't this a strange behaviour in the textbox control? am I doing something wrong? is this what it should happen

any answers are welcome

I would rather use an htmlInputHidden control...

With "visible" set to false, you won't generate any client side HTML for
this control. You are then not able to retrieve the posted values.
For your small test, are you sure you are retrieving the posted value (could
it be just because the textbox is initialized server side this way) ?
