I am doing a validation using javascript. Checking the field for validation. I want to assign the alert message to a label "user control" which is in the aspx page.

I tried
function check()
{
var a = document.getElementById('textboxname');
var stra = a.value;
if(stra.length ==0)
{
document.getElementById('Label1').value = "pls enter the value';
}

}

Pls. help me to solve this I am not able to set the value to the labal.

Hi

you can assing the values using document.form

To access txtFirstName in your aspx page using JavaScript, use:

document.forms[0]['TestControl:txtFirstName'].value

To set txtFirstName, use:

document.forms[0]['TestControl:txtFirstName'].value = 'Naveena'

use the innerHTML property instead of value property.Because labels renderd as a <span> tag and it don't have value property
