Question

How can I change the Text for a CheckBox without a postback?

<asp:CheckBox ID='CheckBox1' runat='server' Text='Open' /> 

I would like to toggle the Text to read ‘Open’ or ‘Closed’ when the CheckBox is clicked on the client.

Answer 1

function changeCheckboxText(checkbox) {   if (checkbox.checked)     checkbox.nextSibling.innerHTML = 'on text';   else     checkbox.nextSibling.innerHTML = 'off text'; } 

called as:

<asp:CheckBox runat='server' ID='chkTest' onclick='changeCheckboxText(this);' /> 

Just FYI, it’s usually bad practice to change the text of the checkbox label because it tends to confuse the user.
