Hi Rajesh,

I assumed:
Button Name: btnSave
Textbox Name: txtAdd

Server side code:

C#

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            btnSave..Attributes.Add("onclick","return checkValidation();");
        }
    }

Javascript code:

C#

function checkValidation()
{
    var txt = document.getElementById('<%= txtAddlientID %>');
    if(txt.value == '')
    {
        alert('Please enter data before save!');
        return false;
    }
   return true;
}

Please do let me know, if you have any doubt.

Solution 3

OnClientClick="return Isnotesempty()";

function Isnotesempty()
{
    if(document.getElementById (objid).value=="")
    {
        alert("Description should not be empty...!");
        document.getElementById (objid).focus();
        return false;
    }
    return true;
}

Happy Coding.
