Which Technology? If WebForms then , keep your third textbox readonly and enable it from code behind "txt3" runat= "server" ReadOnly= "true" > protected void TextBox2_TextChanged(object sender, EventArgs e) { if (Convert.ToInt32(TextBox2.Text)>Convert.ToInt32(TextBox1.Text)) { TextBox3 .ReadOnly= false ; } }

Hi Ramco, Please use this one in Aspx page, "txtBalanceTobePaid" runat= "server" AutoPostBack= "True" OnTextChanged= "txtBalanceTobePaid_TextChanged" > "txtBalancePaid" runat= "server" AutoPostBack= "True" OnTextChanged= "txtBalancePaid_TextChanged" > "txt3" runat= "server" ReadOnly= "true" > Code behind page, protected void txtBalanceTobePaid_TextChanged( object sender, EventArgs e) { EnableTextBox(); } protected void txtBalancePaid_TextChanged( object sender, EventArgs e) { EnableTextBox(); } Private void EnableTextBox() { if (! string .IsNullOrEmpty(txtBalanceTobePaid.Text) && ! string .IsNullOrEmpty(txtBalancePaid.Text) && Convert.ToInt32(txtBalanceTobePaid.Text) > Convert.ToInt32(txtBalancePaid.Text)) { txt3.ReadOnly= false ; } }
