Hi

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.

Chear,
Shalu

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' Please refer this URL http://www.devx.com/tips/Tip/28032 arjun-

use the below code to assign a text to the label. `document.getElementById("Label1").innerHTML = "pls enter the value'";`

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

document.getElementById("Label1").innerText="pls enter value" or document.getElementById("Label1").innerHTML="pls enter value"
