dynamic textbox values

Hi,

While dealing with Dynamic TextBox Controls in ASP.NET you have to consider few things. First, In which event you are creating the control and second are you adding them in Control Hierarchy or not.
If you check the ASP.NET Page Lifecycle, Before Page_Load, there are few methods PreInit(), Init(), LoadViewStateData() and LoadPostBackData() . Most of the developer create dynamic Controls in Page_Load() or In some event like Button Click. But those control will never get the data from LoadViewState() or LoadPostBackData() as control are been created after Init() they are not part of the control hiearchy. ASP.NET Loads Postback and View State data based on the control hierarchy tree which are created in init() events.
So, you have to make sure you are creating the control in proper place. I hope this will helps you to know the internals and you can dig dive!

This article while help you to deep inside of ASP.NET Text box, which I refered many times :) ViewState and Postback[^]

Cheers!!

If you're creating a dynamic textbox then by versa you can also get a value from it back.

Like wise if you can create like

Textbox tx = new Textbox();
Page.Controls.Add(tx);

Then versa it's possible to find it back again from page too

Textbox tx = (TextBox)Page.FindControls(tx);
if(tx != null)
{
string TextValue = tx.Text; // the value you want actually.
}

Store this value to SQL as per requirement.

Or just be more clear with your intention, share snippets, Show some effort, spend some more time on questioning.

People are here lazier than a lazy questioner!
