Jeff, Thanks for the reply.
Hi Gary,
This is because when we post back a page, the Page_Load event is processed
before the Button_Click event. So,the textbox's value is initialized again
in Page_Load before we get it's value in Button_Click.
To resolve this problem, we just need to initialize the TextBox in
"if(!this.IsPostBack){...}" in the Page_Load. Then when we click a button,
the TextBox'value will not be initialized again.
Check this link for more information:
Page.IsPostBack Property

/frlrfSystemWebUIPageClassIsPostBackTopic.asp>
I would also like to recommend one good article to you:

Hope this helps.
Best Regards,
Lewis

| Jeff,

| Thanks for the reply.

| Not sure what you mean by the update command code. I read
| the database and update the textbox through the Text
| property..
|
| AdminCompanyName.Text = companyName;
|
| The Save button click method then executes the sql update
| statement that uses the Text property to update the
| database...
|
| SQL = SQL + "CompanyName = '" + AdminCompanyName.Text
| + "'";
|
| Shouldn't the Text property reflect what was typed into
| the textbox?
|
| Thanks,
| Gary
