Viewstate size bytes shows 0 in trace.axd

[SANJISH]

Hi,

I am using the trace facility to find the viewstate size of controls on postback. I have added a label , a textbox and a submit button to the webform. However after posting my page and viewing the trace.axd page I find that the viewstate size bytes and controlstate size bytes is 0 for all the controls. Can anyone explain why ?

ViewState stores every changed property. Initializing the control in the page (any event) counts as a change, so any changes in control property during page execution will be persisted in viewstate.

But shouldn't the viewstate size bytes in trace.axd show some value atleast instead of 0 everytime i post ?

Add following in click handler of button,

TextBox1.BackColor=System.Drawing.Color.Red;

Hi,
Thanks a lot for the explanation . It worked . However the control state size remains 0 . I am sure you can explain that also.

Thanks & regards

Thanks!

Have a look at msdn articles about ControlState and How it is different than ViewState.
