Solution 1

Ok. So, whats the problem?

In button click event on server side event:
myTextbox.Text = "my dynamic text";

UPDATE:
Based on wait are you asking that some one enters text into the text box, then clicks the button then the value is displayed on the webpage and if they do it again the new value and the previous value(s) are displayed?

This means you want to preserve the earlier text too. Ok.

Codebehind MyPage.aspx.cs:

C#

//define a page level variable OR a hidden field 
// lets name it allValuesOfTextbox
// Now, in button click event:
allValuesOfTextbox += myTextbox.Text ; // if it was a page level variable
someLabelOnWebpage = allValuesOfTextbox; 

allValuesOfTextbox.Value += myTextbox.Text ; // if hidden field
someLabelOnWebpage = allValuesOfTextbox.Value;

Please do not use text-speak (ex - u, r, rit).
This is a technical forum. Please be professional.

see your new question...

Albin Abel 21-Feb-11 8:37am

Sandeep already answered how to preserve the old text. so what is the problem now

Ed Nutting 21-Feb-11 8:40am

Erhem..please note he reposted the question but phrased it differently wich is why I sed see new question. Also, it would have to be a static page object or a session object to retain its value reliably between requests as vlaues of hidden fields and labels are cleared with each request.

Sandeep Mewara 21-Feb-11 8:49am

Oh ok. It looked to me the same thing. Actually, OP is unable to express clearly.

BTW, hidden-fields does not get cleared on each request. Nor does page level variable. Have used them both earlier. All works good.

And as said, session too would work, it's just why to use it until unless necessary. I personally would go with Hidden fields. Good and reliable.

Ed Nutting 21-Feb-11 8:56am

Fair enough I was not aware of that. Thought they did get cleared, nm then. Personally Il stick with Session variables because they make life, and templates, simple rather than having lots of hidden fields all over the place :P Also, whats the hamr in learning to use Session variables anyway? The OP will need to use them if he/she starts to fiddle with things like login etc...

Sandeep Mewara 21-Feb-11 8:57am

:) Well, if you say learning, sure why not!

Ed Nutting 21-Feb-11 8:42am

Oh I would also add that static page objects normally exist for all user requests so all users would end up seeing every others users entries as well as their own. Session solves this problem. If it was as simple as what you suggest, there would be no need for the session object in a lot of cases :P

Sandeep Mewara 21-Feb-11 8:46am

:) I was about to say the same thing for static thing but you got it.

Sandeep is right, you just need to add text to a variable, and then assign the variable to the box:

string fullText = "";
void AddText(string text)
{
    fullText += text;
    //or this one if you want to display multiline text
    //don't forget to set the Multiline property of your text box to true in the designer.
    //fullText += Environment.NewLine + text;
    UpdateTextBox();
}
void UpdateTextBox()
{
    textbox.Text = fullText;
}
