TextBox value and Javascript

Hardy Wang

Guys,
I have a web form with some <Asp:TextBox> controls, on some condition, I
need to trigger a client side JavaScript to clean all values of these boxes,
like below:

function DisableForm() {
document.getEle mentById("UserC trl_Text_97").v alue = "";
document.getEle mentById("UserC trl_Text_97").d isabled = true;

document.getEle mentById("UserC trl_Text_98").v alue = "";
document.getEle mentById("UserC trl_Text_98").d isabled = true;

document.getEle mentById("UserC trl_Text_99").v alue = "";
document.getEle mentById("UserC trl_Text_99").d isabled = true;

document.getEle mentById("UserC trl_Text_100"). value = "";
document.getEle mentById("UserC trl_Text_100"). disabled = true;
}

The problem is, when I click "Save" button, all original data with these
text boxes are posted to server, instead of empty values.

Anybody knows why?

When you disable a control, its values are not posted back. So the control
is pulling its previous value from viewstate.

Client side character count - Textbox

by: Jerry | last post by:

In limiting textbox input to 500 characters I would like to include a dynamic count of characters input while the user is typing into a textbox.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
